Here's a great resource for anyone who uses Microsoft products and thrives on interesting facts and discussions relating to those products. It's the BlogMS Resource Guide - Directory of Product and Support Team Blogs. This directory lists over 240 blogs, and of course, our very own Forefront TMG blog is listed. The directory also makes it easy to sign up for blog RSS feeds.
Another useful resource is the summary of Free Microsoft Software and Online Services: http://blogs.technet.com/blogms/pages/microsoft-free-software.aspx.
