We’re currently working on a consolidated event calendar/list/RSS feed for the Western US. Right now, there are several places you need to go to get a relatively comprehensive list of Microsoft events in your area, including MSDN Events, Technet Events, Microsoft Worldwide Events, and blogs (hopefully this one!).
Are there other places you look? Let me know! Our ultimate goal is to provide you a comprehensive listing of Microsoft happenings in a single location, ideally via RSS feed as well.
Send me mail or comment on this post below and let me know where else you look.
