I was working on an australian focused social network for oracle a while back (almost three years now) and this was an example site given for what they had done overseas, at that point it was also a rails app, and I note in the portfolio it's a rails app too. Higher up in the comments here I can see someone referring to this as an overused enterprise framework, so maybe it's been relaunched using one of oracle's tools? Couldn't be bothered to fiddle with it and figure it out.

It looks pretty much the same to me from memory.
