It looks like Microsoft has finally put together the first installment of a true Resource Center focused on SharePoint.  It has direct links to a lot of existing content that was previously scattered all over MSDN, some of which you might not have seen before.

It is still kind of light on content but we can hope that Microsoft will continue the effort and turn this into a key launch point for all things SharePoint related.
