I recently had a chat with the TechNet web site team and they make me aware of a very cool Social Bookmarking site (on preview). What is social bookmarking? It's quite simple - think of it as a way to share your Internet Explorer favorites via the "cloud" with your friends and colleagues around the world.
For example, you can tag sites like my blog here (Microsoft Assessment and Planning Toolkit Team Blog) or the Virtualization TechNet Solution Center site with the tag "hyperv" or "virtualization." Other viewers may do the same tagging on the same.
What a great way to share, right? Give it a try now! http://social.technet.microsoft.com/
