One of my first projects when I started working here is an ASP.NET Wiki. ScottGu had the idea and my team had to make it happen. The Beta (finally!) launched today. A lot of work went into the development and seeding of this project.
The idea is that folks spend a lot of time trolling the blogs, googling live-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.
Search is great, but for targeted answers you can't beat the one-two punch of search plus human editing. I spent a long time looking for content and seeding the wiki, but there's still piles to do. Hopefully it won't be just me editing it.
What's the point:
You can leave comments on the content, there's RSS feeds, and you add your own updates and make it better. You'll also get recognition points if you're a member of the http://www.asp.net community.
You can get there from http://wiki.asp.net/ and it's also been added to main tab menu of http://www.asp.net. Folks are already starting to discover the site and make changes. I hope you find it helpful!
Thanks above all to my friend Ward for inventing the Wiki in the first place!
