He couldn’t stay away from the keyboard for long.

Steven Sinofsky, the former Microsoft Windows president, launched his own blog today called “Learning by Shipping” — promising to share “thoughts and perspectives on product development, management, and the process of bringing new products to market.”

Sinofsky was legendary inside Microsoft for his lengthy posts, for both internal and public audiences. His departure from Microsoft weeks after the release of Windows 8 followed internal clashes with Microsoft CEO Steve Ballmer, but Sinofsky makes it clear in his introductory post that he won’t be airing any dirty laundry.

He writes, “The focus on this blog won’t be about specifics or the past regarding Microsoft, of course. Some topics might come from current events as the basis of more general posts. … In this new blog, I am hopeful that there can be a rich dialog about the ‘how’ and ‘why’ of building products in our industry and that serves as springboard for posts.”

The launch of the blog comes a few days after Sinofsky officially ceased to be a Microsoft employee. Although he resigned on Nov. 12, he technically remained an employee through Dec. 31.

Sinofsky will be an executive in residence at Harvard Business School this spring, but he hasn’t yet said what he plans to do next in his career.
