Hello,
Why not include Heatware, Paypal verified, ebay information marketplace trading?
Global reputation ratings are not very useful and easy to game.
The GPG web of trust concept is far superior IMO. It's already in place at bitcoin-otc.
I was going to go read up on the bitcoin-otc web of trust thing since I've been meaning to anyways, then realised there are probably many others like me who are curious about that system on this board. Would somebody want to describe it and/or how to participate in it without being an IRC expert?
