From the L.A. Times Technology blog:

Evan Williams is spending less time these days around the San Francisco offices of Twitter, a company he co-founded and once ran as CEO.

But Williams isn’t gone from Twitter altogether — despite former Chief Operating Officer Dick Costolo taking over as chief executive last fall, and fellow co-founder Jack Dorsey taking over Williams’ post-CEO role of leading product development.

 ”As was reported in various places yesterday, I’ve decided to scale back my role at the company. (I’m still involved, but it’s no longer my full-time job.),” Williams wrote in a post on his personal Evhead blog.

“I’m not ready to talk about what I have planned next, but I will venture a prediction about what’s next for Twitter: It will be bigger and better.”
