Read it. Especially if you work in software development.
(On an unrelated note, I upgraded my Linux desktop at work today to Fedora Core 2 from Red Hat Linux 8 because I needed a newer version of PHP to test something and it was such a dependency hell (PHP meant upgrading Apache, that meant... etc.) that I figured I may as well just upgrade the box in general. I'm glad I did - lots of stuff bumped, and the new versions seem nicer in general. I'm also playing with Yum for the first time and it seems pretty cool.)
