If you're really curious about VSTS and blogs aren't giving you enough regular info, and you use an RSS aggregator for getting your information, consider subscribing to the following MSDN Forum RSS feeds:

VSTS Software Developers:

Actually, all of the MSDN forums have RSS feeds so you can pick the ones you want.  These are just two that I'm on.
