Being a little behind in my blogs, I just today read that Sara Williams has left Microsoft.
You may not have heard Sara's name before, but you certainly know about the projects she's worked on. Sara had the ability to go against the current and do things that changed Microsoft for the better. Things like GotDotNet, developer centers on MSDN, the developer feedback center on MSDN - Sara was involved in all of these things, and in many cases, she was *the* driver behind them.
In addition, she was a genuinely nice person.
She will be sorely missed.
