looks like they're forcing RIPPLE which people like me don't know how to use
I can explain that (I think). You find a USD Gateway on Ripple. Lets call that place usRipGate. Now you (lets call Joe) deposit money into usRipGate, then they send your deposit to you as a usRipGate:IOU. Now you (Joe) take that IOU and you trade it on the ripple peer-to-peer exchange for a bitstamp:IOU. Now the assumption is that there will be users on bitstamp who are holding dollars trying to get the money out. Lets call one of the users Sam. So Sam has money in USD in BitStamp he is trying to get out to usRipGate, and Joe has money at usRipGate he is trying to get into BitStamp.
Joe and Bill trade IOUs. Now this process is not 1:1. Joe is putting a BitStamp:USD:IOU "bid" on the ripple order board, and Sam is putting a BitStamp:USD:IOU "ask" on the ripple order board.
Last month the Bid:Ask spread was sitting at 14% (OUCH!).
Rumor has it that both sides are working to increase liquidity to bring that down. I for one don't want my $100 US stateside to turn into $85 US in the EU. That about as bad as a mt.Gox wire.
Disclaimer: I have no idea what I'm talking about, so if my Ripple logic is off, don't blame me... I just post here.
