Mike Shaver, one of the founders of the Mozilla project and longtime VP at Mozilla Corporation — the maker of Firefox — has announced that he’s leaving Mozilla Corp. Shaver has worked at the company for the past six years, holding positions including VP of Engineering, and, most recently, VP of Technical Strategy.

He’s well known in the open source and Mozilla communities, and his departure has led to quite a few responses on Twitter and elsewhere (he jokes that he might add his @reply stream to his resume).
