I've been reading a lot of stories lately about developers leaving the friendly confines of .NET Land for Rails and other non-Microsoft technologies.  Perhaps the most notable being Mike Gunderloy of  The Daily Grind fame.  You can read more about Mike's journey over on his A Fresh Cup - Notes from a recovering Microsoft addict blog.  Also of interest is the Forums on the softiesonrails.com site. 

I actually thought about switching my blog engine over to Mephisto to get a little taste of Rails, however, since I'm hosting this on a Windows box the thought was short lived.
