A while back, I wrote a piece about Comparing Content Management Systems.  My colleague Kat Lehman in the Diocese of Bethlehem has found a nice link and a fairly comprehensive list of CMS options. She compiles a great little e-newsletter called [email protected] House which I commend to you to check out.  Lots of good stuff.  To get on the list to receive this newsletter, you can contact her via email and follow her on Twitter @KatLehman.
