Professional linkbaiter Guy Kawasaki reports a "juicy tidbit" from the Gnomedex conference in Seattle: "Adobe is scratching their collective chins and in deep thought considering a Yahoo acquisition." We don't believe it. With a $23.61 billion market cap, Adobe isn't exactly in a position to spend $40 billion on Yahoo, even its stock price has finally sunk below where it was when Microsoft made its offer. So why the rumor? Look to its source: Chris Pirillo — the guy who puts on the Gnomedex conference, of which we admit to only a vague awareness before Pirillo sent a Twitter message about the rumor and got everyone talking about it. And him. And his conference.

Chris Pirillo, the tech pundit and conference organizer, doesn't mind being exposed. But he does object to people stealing his identity, as some unknown user has done on Pownce, Kevin Rose's file-sharing service. Pirillo says he hasn't signed up on Pownce, and doesn't know who's using the username "chrispirillo" on the service. Among the people the faux Pirillo appears to have taken in, if you can trust any username on Pownce: Digg cofounder Jay Adelson, spokesblogger Robert Scoble, and Internet-TV personality Veronica Belmont. One thing Pirillo might want to look into: Someone has also signed up for Pownce with the login "lockergnome," the name of Pirillo's popular tech website.

"You can help? 'Cause I can get Web 2.0 to work on my Mac, but not on Windows Vista...I went to Best Buys and they gave me Web 1.0, but that didn't work on Vista." So says Chris Pirillo, tech commentator and wit, in this video conversation with some telemarketers. [YouTube]

Here's a hit of news for all you crazy-uncle-watchers out there.

I am as tired of Rocketboom split-up news as you are.

Okay, since everyone asked, here's your fanservice. Now geez, Robert Scoble, stop with the booty calls.

Hoo boy, four San Francisco conferences in one week! Starting with today's MashPit, this week is a con junkie's dream, as long as you have a guide to getting through.

In the booming Silicon Valley economy, everyone's looking to buy or be bought. But not all offers are equal. How do you politely turn down a lowball without burning your bridge? Let's take a look at three turn-downs — none of which were publicly reported.

As always, the wittiest people on Valleywag are the commenters. This week's best:

Right, with all these geeks taking their clothes off, it's time for a recap. Shield your eyes.

Two blogging pundits set up challenges, one for himself and the other for "two kids in high-school and a couple of cases of Red Bull." Which is more likely to fail?
