How many ex-Yahoo managers does it take to reproduce a classic Beatles album cover? From left to right: Salim Ismail, Chad Dickerson, Scott Gatz, and Bradley Horowitz. All four were, at some point, responsible for parts of Yahoo's advanced-products group, including the Brickhouse incubator in San Francisco. The band reunited last night at the 21st Amendment bar in San Francisco's South of Market district to bid Dickerson farewell; he is leaving Yahoo to become CTO of Etsy, the Brooklyn-based marketplace for hipster-friendly handicrafts one must nod politely about. Ismail is attending to Confabb, the startup he failed to sell before joining Yahoo; Gatz is now running GayCities, a queer-travel website; and Horowitz is now at Google.

Baptiste, for "One bubble Pete Cashmore would like to pop."

In what seems like another age, my predecessor once wrote about companies' "blogger appeasement groups" — units dedicated to generating buzz, not bucks. With Chad Dickerson leaving Yahoo Brickhouse, the troubled company's troubled incubator for new ideas, I think we can declare the delusion of blogger appeasement groups safely over. The self-appointed punditocracy of the blogosphere never was a real customer — nor even a twisted proxy for a real customer. Playing to the echo chamber only generated noise — a specialty of former Brickhouse head Salim Ismail.

Chad Dickerson, who has been responsible for Yahoo's Brickhouse incubator since December, is leaving the company to be CTO at Etsy, an online handicrafts retailer. We hear Google, where former boss Bradley Horowitz now works, had been heavily recruiting Dickerson. With this move, Dickerson has deftly dissed both Web giants. Well done, Chad! [TechCrunch]

Whatever side you're on, everyone agrees that Twitter's problems with downtime come down to one man: Blaine Cook. Cook's advocates claim he was hobbled from fixing the site by incompetent managers; Cook's detractors say his decisions as Twitter's chief architect led to its frequent outages. We'd heard he left Twitter with plans to relocate to the U.K. Instead, we've learned, he took a job at Yahoo's Brickhouse, the troubled San Francisco office meant to incubate new projects. He's believed to be working for Chad Dickerson, who recently listed a position for a software engineer experienced in the Ruby programming language — one of Cook's specialties.

Facing a takeover bid from Microsoft, Yahoo has pinned its hopes on new product launches from its best and brightest. In less than 11 hours, one of them, developer Tom Coates, will take the stage at ETech, Tim O'Reilly's conference outside San Diego. His mission: to roll out the long-delayed Fire Eagle, a system for announcing your physical location to other websites. Possibly. This evening, Coates has been announcing his location, and his situation, via Twitter. He's in Carlsbad, the site of the conference. Things are not going well: "Listening to Chopin. It is not calming me the fuck down. Grr!" In other Twitters, Coates moans about the number of tasks left to do. While he doesn't specify, it's hard to imagine he's doing anything but fixing bugs

Yahoo Video has soft-launched a new website, in a move which speaks to both the potential of Yahoo and the company's utter disorganization. It has all the necessaries in the age of YouTube and Hulu: clips created by amateurs and professionals, playlists, and "exclusive" content. The latter, if true, is refreshing: Thanks to syndication deals which allow the endless regurgitation of video from site to site, most of the Hollywood-born clips on the Web are numbingly similar. The site also has a tantalizing promise: Video on Flickr.

As we reported first, Yahoo's Scott Gatz confirms he's leaving. Chad Dickerson will move from the Yahoo Developer Network to take over running Advanced Products. This is hardly a promotion for Dickerson; we hear he had a falling out with his boss at the developer group, ex-Microsoftie David Sobeski. Dickerson is now in charge of someday making Fire Eagle a real product. He also gets to work oh so closely with professional conference attendee Salim Ismail. And that brings us to our career advice for Dickerson.
