Netflix Inc (NASDAQ: NFLX)

Amazing. Amazon.com Inc (NASDAQ: AMZN), that big online retailer, sees the flix for the net. The shares keep rising for the online DVD rental company-up about 15%, highest since January-- even if their discs do come a little scratched. More than that though is while new subscribers are coming on; it's not exactly going gangbusters. Still, 6.8M is a whole lot of subscribers. Will Amazon, or someone else, overpay?

Rackable Systems Inc (NASDAQ: RACK)

Which came first: The ongoing takeover rumors or the higher stock price? Or was it that Dell Inc (NASDAQ: DELL) is said to be after Rackable, a provider of servers and storage products for high density data center deployments. Rack it up.

Feldman Mall Properties Inc (NYSE: FMP)

Word is that this real estate investment trust will look for a sale, combo or merger. They said the venerable firm of Friedman, Billings, Ramsey & Co. will help them "explore strategic alternatives." Then the stock went up.

STILL FLYING AROUND

Trump Entertainment Resorts Inc (NASDAQ: TRMP)

Dennis Gomes, whose name surfaced in March, is a one time gaming exec and regulator. He's signed a confidentiality agreement to have a look see at the firm's Atlantic City casinos. Separately, Las Vegas' Boyd Gaming Corporation (NYSE: BYD) has also been mentioned as a possible contender.

YRC Worldwide Inc (NASDAQ: YRCW)

The CEO of this Kansas-based transportation service provider has been quoted as saying that a takeover is possible. An LBO is likely. This week the shares have actively been trading up.

Dollar Tree Stores Inc (NASDAQ: DLTR)

Imagine a dollar tree where the stock keeps going up, up, up. Well, here it is, once again, a subject of takeover talk.

Blogger David Berlind was browsing around in Technorati and found a strange error. He checked again, just to be sure, but it appeared that his Technorati error was causing a Yahoo! 404 Not Found message. He wonders if Yahoo! has acquired the leading blog search engine.

If the buzz is true, it will prove TechCrunch's Michael Arrington (and Red Herring's Liz Gannes, who quoted him) to be one heck of a prognosticator. Back in January, he asked, "When Will Yahoo! Acquire Technorati?" and noted that Technorati CEO Dave Sifry had declined to comment on the speculation.

"No Comment" has never been proof of anything, but strange errors may be at least evidence enough to start the rumor mills churning. Interestingly, both Technorati and Yahoo! are spending a lot of time this week talking video; Technorati struck a deal with Paramount to help create buzz about new movies, and Yahoo! previewed its new home page with (of all things) video right there front and center.

Yahoo! was solidly up in trading today, 53 cents, to $29.53, and has soared in after hours -- up over 4% since yesterday's close. Everybody loves a rumor.
