(2011-07-21) Twitter Dorsey Purges Product People

Jack Dorsey has dumped 4 Product Manager-s at Twitter. This move is said to be led by Dorsey as a final measure to remove those still closely affiliated with the old Evan Williams, Biz Stone, and Jason Goldman regime. Those three, of course, all left Twitter in recent months and just re-launched the Obvious startup incubator where Twitter was originally born... The move was led by Jack Dorsey and will see key product guys Kevin Cheng, Josh Elman, and two others we’ve yet to confirm, leave the company... Update: We’ve now confirmed that Anamitra Banerji (@anamitra), who started Twitter’s ad platform, and Jean Paul Cozzatti (@jeanpaul) will round out the foursome of PMs who are leaving. Interesting update on 2011-03-24-DorseyReturnToTwitter.
