Which is saying something. Because as you might recall, in 1999, Nasdaq was soaring on the back of the dot-com bubble to levels never before seen.

And here we are amid the worst recession since the 1930s. Haven’t even entered that “all important holiday shopping season” yet, either.

Things are looking pretty good for Amazon (AMZN) right now. Sure, there’s renewed competition from retailers like Wal-Mart (WMT). There are potential sales tax issues and income tax liabilities and a raft of Kindle-killers headed to market. But Amazon’s stock is up 131 percent this year, brokerage firms are upgrading their ratings on the company, and analysts are saying it’s only going to go higher.

Said Citigroup analyst Mark Mahaney: “Near-term outlook very positive as AMZN heads into holiday season fully armed against shrinking/de-stocking offline retailers, with one of the must-have gadgets of the season (Kindle), a significantly strengthening International presence, and soon-to-be closed Zappos acquisition.”

Yeah. Things are looking pretty good right now. But we said that back in ‘99 too–when Amazon had a similar P/E.

Now, $500 a share isn’t in the same stratospheric price range at which Google’s stock once traded–certainly it’s not the $707 and $713 it reached in 2007. But it’s a psychological milestone nonetheless, and that’s worth noting because Google’s shares have risen more than 50 percent over the past six months, and Wall Street seems to be growing increasingly more positive on the stock.

Sadly, the same cannot be said for Yahoo (YHOO), which hasn’t elicited the same sort of response. But then why should it? As Yahoo CEO Carol Bartz said earlier today, “Yahoo and Google are different companies. They are in different businesses….They aren’t us and we aren’t them.”

Clearly. Yahoo shares are trading at what, $16?

Seems the Street would have much preferred the “boatloads of money” Yahoo CEO Carol Bartz once said she’d demand for a search deal, than the “boatloads of value” she claims to have given them this morning. As I write this, Yahoo (YHOO) shares are trading down more than 12 percent at $15.14. Microsoft (MSFT) shares are up 1.41 percent at $23.80.

Below, a roundup of analyst notes that have been issued on the deal.

Jeff Lindsay, Bernstein Research: We believe Yahoo!’s search deal represents a significant positive for the company’s economics, as both Yahoo! and MSFT were too subscale to compete effectively versus Google. Although the combined 30% search share is still less than half the size of Google, both Yahoo! and MSFT will realize significant cost savings from combining their search technologies. In addition, the greater scale should increase the effectiveness of the search engine, driving revenue synergies through improved search monetization.

Sarah Friar, Goldman Sachs: We view the deal as positive for Microsoft as terms are better for the company than had been speculated (no upfront fee; 88% TAC) and the combined market share provides scale to drive efficiency and legitimacy/relevancy for Microsoft’s online investments. Yahoo!’s $3.0 bn/year search sales translates to $360 mn/year for Microsoft in revenues. Microsoft will incur incremental expenses when the deal closes (expected early CY10), but limited (if any) impact on FY10E and while investments will continue into FY11, our model already assumes sizable expenses.

Douglas Anmuth, Barclays: YHOO-MSFT terms not nearly as favorable as anticipated, but we believe deal is neutral to the co’s L-T positioning. We would have liked to have seen an upfront payment, higher TAC, & rev share on Bing.com searches among other things, but we like that YHOO maintains ability to sell search adv, & therefore relationship with its largest advertisers. It’s unclear how favorable the deal will be to YHOO over time, but our fundamental reasons for owning shares remain the same. We expect better execution on the audience & content biz & specifically within display adv., & we believe YHOO will be able to take out a meaningful amount of costs from the biz aside from search tech. over the next couple yrs.

Peter Misek, Cannacord Adams: We are relieved that Microsoft did not have to provide an upfront payment as part of this deal while effectively garnering more scale. This deal provides Microsoft with a much needed boost in competing with Google (GOOG : NASDAQ : US$435.00 | BUY) as its search algorithm, Bing, is being catapulted to greater market share. In addition, utilizing Yahoo!’s sales force for premium search will allow Microsoft to lower expenses over the duration of the partnership while attempting to attract a greater level of advertisers for the combined platforms. We believe this is a much needed relief for Microsoft, but is one step in a greater battle. In the end this doesn not solve Microsoft’s competitive disadvantage with Google. Rather we think it accelerates Microsoft’s desire to think outside the box and come up with a non-linear way to catch Google.

Heath Terry and Andrew Thomas, FBR Capital Markets: The lack of an up-front payment, no minimum revenue guarantee, and a revenue share that, while above average, is slightly below the +90% that larger deals command make for a lackluster deal for Yahoo!, in our opinion. The lack of any display component to the deal also seems like a missed opportunity for the company. As we see it, the only financial benefit to Yahoo! is the ability to shed the not insignificant technology costs associated with running a search engine. According to the company, this should result in an annual benefit to GAAP operating income of $500M….Restructuring these two businesses and untangling them from their existing partnerships and internal ties will be a massive organizational challenge for both companies.

Mark Mahaney, Citi Investment Research: Implications For YHOO – Positives: 1) YHOO believes deal would generate incremental $250MM in annual cash flow (17% accretive to our ’09 est)–assumptions very hard to test, but magnitude is reasonably conservative; 2) 88% TAC is higher than industry average, but as expected given deal size. Challenges: 1) No upfront payment to YHOO is a negative vs. expectations, tho guaranteed RPS provides significant backstop; 2) Lack of display advertising deal is a negative vs. expectations; & 3) Acknowledgment of YHOO’s Search technology limitations.

Todd Greenwald, Signal Hill Capital Group: The deal announced today will take a very long time to come to fruition we think, and will face several challenges–it will face regulatory hurdles given Microsoft’s antitrust history (though we’d expect it to ultimately get through given Google’s dominance). Additionally, it seems hard to fathom operationally, as it will require Yahoo’s salespeople to be selling Microsoft’s technology. Advertisers will want one point of contact (which would be Yahoo), though that point of contact won’t be entirely responsible for what they are selling–instead of bringing in an engineer from within the same building, the Yahoo salesperson may have to coordinate with a Microsoft employee up in Redmond. Not impossible, just tricky. And considering how smooth and automated the process of buying ads is on Google’s platform, this could prove to be a competitive disadvantage.

Mark May, Needham & Company: Search advertising is not a zero sum game, in our opinion. If Microsoft is able to make Yahoo! (and Microsoft) search more effective through this deal/combination, then we believe is will result in advertising spending more on the new search platform but not less on the Google platform. A more effect Yahoo!/Microsoft search platform does not mean Google search becomes less effective, and we believe there is more demand than supply for effective search marketing. The dollars will likely come from other, less effective, buckets.

Business 101 convincingly argues that most large M&A deals and partnerships are not successful. And, most large-scale Internet media M&A deals and partnerships have tended to under-perform their original promise (e.g., AOL Time Warner, Google/MySpace, etc.). Moreover, in the case of Yahoo!/Microsoft Search, you have two very different cultures and an expected 24 month transition process. The odds are stacked against this deal having a meaningfully impact on Google. And, over the next 2+ years while Yahoo! and Microsoft are trying to transition, Google will be innovating.

BoomTown provided continuing coverage of the Yahoo (YHOO) merry-go-round. This time, PR head Jill Nash announced her departure. As the company’s chief communications officer, she’s had a challenging two-year run. New CEO Carol Bartz definitely has some PR ideas of her own, including offering cash prizes to employees who provide info on their colleagues who leak information to the press. Not a huge deterrent yet, apparently–it didn’t take long for BoomTown to get info on both Nash’s farewell memo and Bartz’s bounty system. Next, New Networks, the publisher behind BarelyPolitical and its hugely viral Obama Girl videos, has widened its purview to include the tech sector with BarelyDigital, which the online network has envisioned to include regular shows, tech news remixes and the like. It’s rumored that Obama Girl will be making a cameo appearance or two. If the first two features are any indication, the future looks pretty funny. In another round of executive musical chairs, Time Warner’s (TWX) AOL ad head Lynda Clarizio will be leaving the online service, to be replaced by former Yahoo ad exec Greg Coleman. Microsoft (MSFT) is launching a slick new celebrity site on MSN called Wonderwall, created, designed and produced by BermanBraun Interactive, a Hollywood company run by former Yahoo media chief Lloyd Braun. And speaking of musical chairs, MSN is clearly upping its content ante–earlier this week, it hired Yahoo’s recent media head Scott Moore, who used to work at Microsoft.

MediaMemo asked: What happens when one of the world’s richest men lets loose a swarm (a small swarm) of mosquitoes at a high-end conference? Nothing too exciting, really, but when you consider that the stunt was the publicity-generating part of Bill Gates’s talk at TED, which was a discussion of malaria and some of the problems the Bill and Melinda Gates Foundation is facing head-on, it gets pretty compelling. Kindle 2.0, the new generation of the device dubbed the “iPod of the book world” will be unveiled Monday at a New York press event, but how many of the devices have been sold thus far? Amazon’s (AMZN) not telling, but Citigroup analyst Mark Mahaney estimates the number at 500,000–and believes that the Kindle will be a $1.2 billion business next year. Obviously, a lot will depend on Monday and the new device’s reception. MediaMemo also took some time out this week to wish Facebook a happy fifth birthday, and to stack its track record next to Google’s at the same age, with interesting results. Even the pros are getting hit hard these days–in its quarterly earnings report this week, News Corp. (NWS) missed its estimates, recorded an $8.4 billion write-off and lowered its guidance. CEO Rupert Murdoch admitted that the downturn is worse than he thought. He also admitted that he spent $2.8 billion too much for Dow Jones. (News Corp. is the owner of Dow Jones and this Web site.)

Digital Daily followed the trial of four Google executives this week on criminal charges of defamation and breach of privacy after a much-publicized two-year investigation. Google (GOOG) insists the charges are unwarranted and “akin to prosecuting mail service employees for hate speech letters sent in the post.” Clearly, the ultimate outcome will have a huge impact on the future of a free, open Internet. MySpace said this week that it has identified and ousted 90,000 registered sex offenders–and those are just the ones brilliant enough to use their real names. There’s no way of knowing how many are actually using the service or how to prevent them from re-registering once they’re deleted. A free an open Internet, indeed. DD also pondered the future (or lack thereof) of the Motorola (MOT) handset division. Co-CEO Sanjay Jha says the company is committed to making the business work, but its products are looking boring and outdated, and a turnaround would be prohibitively expensive to execute. In the words of one analyst, the company’s problems are “gruesome.” On the other end of the spectrum, Microsoft continues to vehemently deny reports that it’ll be producing its own smartphone. In a report this week, analysts from Broadpoint.AmTech speculated that the device could be uncrated later this month at the Mobile World Congress in Barcelona. Meanwhile, it’s been up in the air for two years whether or not iPhones will ever be uncrated in historic Georgetown. Apple (AAPL) has been around the table a few times now with preservationists wary of the architectural impact of an Apple store, no matter how much the business traffic is needed in the neighborhood. Looks like perseverance may have finally paid off, though–Georgetown’s Apple store could open later this year.

In Personal Technology this week, Walt Mossberg took a look at a program called Foxmarks, which sets out to synchronize bookmarks among all of your browsers and all of your machines. Sound a little too handy to actually work well? Walt found it does a pretty good job, with a few caveats. In Mossberg’s Mailbox, Walt responds to readers who want to know more about doing “techie” maintenance on their PCs to keep them running well, whether or not to buy a 15-inch MacBook Pro, and options for email within Windows 7, which won’t ship with a built-in email program. In the Mossberg Solution, Katherine Boehret tests Google Latitude, an opt-in program that lets users track one another’s movements on their smartphones using GPS, Wi-Fi, and cell towers. Kind of like Gawker Stalker, only with permission and without Lindsay Lohan (unless you happen to be Lindsay Lohan).

Last but not least, Silicon Valley lost one of its own this week. The widely admired and much loved Mike Homer, whose rare, severe illness was a rallying point for many over the past months, passed away last weekend and was laid to rest on Thursday.

More next week.

We continue to be big fans of this product. And we continue to believe that Amazon has a hit on its hands with this device. The problem is that Amazon (AMZN) sold out of these devices way too early this holiday period. And Amazon still doesn’t have International versions available. Hard to see a premier consumer electronics company (e.g. Apple) (AAPL) making these types of errors. But then again, Amazon isn’t a premier consumer electronics company.”

– Citi’s Mark Mahaney on the Kindle

But according to McAdams Wright Ragen analyst Tim Bueneman, who’s actually, you know, spoken with some Amazon (AMZN) officials, the device might not be selling as well as Mahaney claims. “[Amazon] told us that the Kindle is definitely selling very well, but they also said the analysts and reporters giving out these extremely high estimates ‘did not run them by company,’” Bueneman wrote in a research note to clients that also confirmed that there are “several new, improved versions of the Kindle in the works.”

“Extremely high estimates?” Sounds like Amazon’s trying to temper expectations, doesn’t it? And, perhaps, to live up to them at the same time. The retailer announced a new promotion today that will knock $100 off the Kindle’s $359 price until Sept. 8. That ought to boost the device’s sales numbers, whatever they are.

380,000 Kindles sold. That’s double Mahaney’s May prediction. And it’s an important number historically. “In its first year, that’s exactly how many iPods were sold,” Mahaney wrote. “Turns out the Kindle is becoming the iPod of the book world.”

But is it really? And on what sort of data is that pronouncement based? Amazon (AMZN) itself has disclosed no actual sales data for the Kindle. The company said only that the selection of titles available for the device has jumped 67 percent since its launch. Surely it’s impossible to extrapolate sales of 380,000 from that figure alone. So on what other data is Mahaney relying here? Just this, apparently:

1. An anonymous source recently told TechCrunch that Amazon has shipped 240,000 Kindles. That’s shipped, not sold.
2. Kindle tops Amazon’s Bestsellers in Electronics list
3. Kindle has more than 4,000 customer reviews, quite a few of them positive.

Not exactly an abundance of hard data, is it? Which is not to say that the Kindle isn’t well on its way to becoming the iPod of the book world, just that we won’t know for certain until Amazon tells us with hard sales figures.
