KBAlertz

If you haven’t run across this little gem then by all means go check it out.  KBAlertz is a website that is dedicated to bringing you updates when new Knowledge Base Articles from MS are posted.  You can sign up and have them delivered to you via email, or you can select from a number of RSS feeds.  I just subscribed to the new 2005 line of products (.Net 2.0, SQL 2005 and VS.Net 2005).  If anything it keeps you up to date.
