@ev Tells Twitter to Keep in Touch, Have a Nice Summer

Evan Williams this afternoon acknowledged he is no longer at Twitter full time and that he has stepped back from the company in the six months since he handed the CEO role to Dick Costolo. Williams thanked and praised the Twitter team and said they are bound for bigger and better things, in a tone evocative of a high school yearbook note.

Williams’s post, the first substantive one on his personal blog in more than a year, comes a day after Jack Dorsey, Twitter’s inventor and original CEO, announced he would return to work at the company as executive chairman in charge of product.

Williams and Dorsey have flip-flopped their way into and around Twitter since 2008, when Williams replaced Dorsey as CEO with himself. Fittingly, Williams–who spent the winter enjoying the snow in Lake Tahoe and growing a beard–kept Dorsey’s name out of his missive.

But Williams is not out of the game altogether, he said, indicating that a new project, or at least some brainstorming, is in the works.

[N]ow that Twitter is in capable hands that aren’t mine, it’s time to pick up a whiteboard marker and think fresh. There are other problems/opportunities in the world that need attention, and there are other individuals I’d love to get the opportunity to work with and learn from. (Details to come.)
