Ruby on Rails was a wash, for me anyway. I started digging into it and just kept hitting limits on what Rails could handle. "That's Okay, because it's extensible!" I hear those wacky Ruby folks say. But the fact is that I can run rings around anything I can do in Ruby with Perl. Sure, there are some nifty shortcuts, but Perl is very deep, and experience counts for a whole lot when facing a deadline.
So, for now, I'm sticking with what I know.
