Not sure if this should go in the PHP forum or the Ruby forum, but since this one is new and needs more posts, I'll put it here.

I'm curious to hear from people who have used both, how does PHPonTrax (which calls itself and RoR clone), compare to Ruby on Rails?

Off Topic:

Does anyone else find it funny, that 37Signals, the people who invented Ruby on Rails, use php-based PunBB for the Basecamp forums? :P http://www.basecamphq.com/forum/
