Greg Hurlsman at squaretwo.net points out a valuable resource that I have been using for some time (since well before I started "blogging," [insider comment: yes, I put that word in there just for Erik ] to be sure).

KBAlertz.com allows you to browse, search, and receive notifications of new KB articles related to Microsoft products of your choosing - It's really a must-have resource for system administrators and anyone responsible for understanding and maintaining Microsoft products. It does the hard work for you, and let's you get exactly the information you need. You can subscribe for email notifications, and the emails are formatted nicely and can be delivered on the schedule you choose.

The article at Squaretwo describes how to get the same information via RSS - which is very cool. I use this capability and have found it a great way to catalog articles about the products I am most often dealing with in my job. Anyone who's into RSS and has to deal with maintaining systems or programs, check out the article.
