CEO Dick Costolo and Dorsey himself both tweeted the news, announcing Dorsey's return to the company on a day-to-day basis. Dorsey will become Executive Chairman, according to their messages. It's not the title of Chief Product Officer, that some have assumed he'd take, but that does appear to be the role he'll be filling.
Despite his return to Twitter, Dorsey says he's still fully committed to his current startup, Square, where he will remain CEO. "200%" he says in his tweet, indicating he'll be doing double duty at both of these companies.
Dorsey was the company's first CEO, but was replaced by Ev Williams in 2008. Williams stepped down last year, handing the reins of the company over to then COO Dick Costolo. According to a company statement, Williams is no longer involved in the daily operations at Twitter, although he will remain on the Twitter board.#dickbar on the iPhone and clashes with the developer community over changes to the API.
Will Dorsey's return have a positive impact on the direction of Twitter, or as some suspect, will it signal further shake-ups at the top of Twitter's power structure?
