So, we had a slightly crazy idea at Channel9 - why not encourage our users to add/edit/refactor their own wiki pages of feedback about Microsoft products? I kicked things off by creating pages for Internet Explorer and Visual Studio, and the wiki has since grown to include feedback about the .NET Framework and Visual SourceSafe.
Want to join in the fun? Got a gripe or suggestion about a Microsoft product? Read the introduction at http://channel9.msdn.com/ShowPost.aspx?PostID=1413, create an account, and start Wiki-ing.
