Welcome to the Microsoft SharePoint Products and Technologies Community Portal!
This is an experiment. Yes, we are "eating our own dogfood" by using our product (Office SharePoint Server 2007) to power our new community portal, which shall be your starting point for the worldwide SharePoint community.
We aspire to make "SharePoint" synonymous with "community" as much as it already connotes "sharing" and "collaboration."
So, welcome, give us plenty of feedback and enjoy the ride!
