This is a good step. L.E.'s main mechanism for getting involved will be on the seller side, since the buyer side is the weakest in terms of information. Also it will discourage scammers from getting into the game (although I'm sure it's already pretty hard to scam inside of the escrow structure - any transaction outside of escrow has nothing to do with SR and the responsibility lies solely on the participants).It would also be interesting to see what the bidding is up to. If a seller is serious, he's not going to mind throwing down a few bitcoins to get into the game and you are more likely to get sellers who have good sources (or are their own source) providing services and products. This will increase the overall quality of goods on SR, which is of course to the benefit of the customers.Bottom line - I like it!
