Twitter's Evan Williams Confirms Departure

Twitter's Evan Williams on Tuesday confirmed that he will scale back his role at the micro-blogging company and pursue other, unnamed ventures.

"I'm still involved, but it's no longer my full-time job," Williams wrote on his personal blog.

He will remain on the Twitter board of directors and pledged to meet frequently with the company's staff "to help in any way I can."

As for what's next, Williams said he was "not ready" to talk about where he's going, but he did say it was "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," he wrote. "Details to come."

The announcement is not a huge surprise. Williams stepped down as Twitter's CEO in October and said at the time that he would focus on product strategy, but reports soon emerged that Williams was no longer involved in the day-to-day goings on at the company.

There's been a bit of executive musical chairs going on at the micro-blogging company in the past few months. Dick Costolo took over for Evans as CEO last year, and just this week, Twitter co-founder Jack Dorsey announced plans to return to Twitter as executive chairman. The company's other co-founder Biz Stone is also working with AOL as an advisor on volunteer efforts and philanthropy, though he is still with Twitter.

Most of Williams's blog post was spent paying tribute to the team at Twitter, as well as his former company, Blogger.

"It will be bigger and better," Williams said of Twitter. "I have the utmost confidence that, like Blogger, Twitter will grow an order of magnitude more (even though that's a much taller order, given its size already). The momentum is just incredibly strong, critical mass has been reached, and the dark days of imminent technical meltdown are over."
