Proposal: SharePoint Overflow
I think that a site driven by user questions will provide better coverage of the possibilities of SP 2010. There are too many blogs on the Internet that solve every SP 2010 problem by opening Visual Studio and guiding the reader through some C# code.
In fact, SP 2010 has a number of other ways to develop solutions that are geared to a variety of different levels of technical competency. I think that this style of Q&A site will draw out more of the variety of ways to solve a problem and document the tradeoffs of different solutions.
