Earlier today, we asked about Yahoo's Brickhouse — the ostensible incubator of innovation in San Francisco's South Park charged with reviving Yahoo's reputation for Web cool. Departures from the Pipes project, the only notable product release from Brickhouse, raised questions about the operation. Brickhouse head Bradley Horowitz thinks his group is "thriving," but a recent ex-Brickhouse employee reports otherwise. His complaints range from the petty (the office "smelled like dirty socks") to the more troubling (Horowitz, he claims, "suffers from god syndrome and needs to get over himself"). The full email, after the jump.

Remember Yahoo Pipes, the "interactive feed aggregator and manipulator" — in other words, a website meant to help people build simple Web applications? It launched to some fanfare last February, with many taking it as a sign of Yahoo getting its mojo back. We hear that the project is starting to "implode," as our tipsters says, with most of its upper-level people looking to get out. Already gone, Wired's Epicenter notes, are the two cofounders of the project, Pasha Sadri, who left to pursue a "personal project," and Edward Ho, who just joined rival Google. Pipes was the first major release out of Yahoo's Brickhouse, the company's San Francisco-based startup-idea incubator. That Brickhouse's door is revolving so swiftly after six short months isn't a good omen to us. So, how are the rest of Brickhouse's projects faring? If you've heard anything, please fill us in.
