While having little to no experience of Ruby/Rails, I have heard great things about it and if my experiences of python very recently are anything to go by I can certainly see myself delving into Ruby on Rails soon. I'm voting yes because once I start to tinker I usually want a place to start showcasing my handywork and letting people play with it themselves
EDIT: For those looking for a quick intro to what Ruby and Rails is in general and how it can be used, this page on the Rails wiki is quite handy:
