I also totally agree on the "currency". Euro has been proven to be more stable than the Dollar.
Hopefully, the guys at Matchbook would listen to our constructive "suggestions" on how to make Matchbook everyone's favorite betting exchange.
Right now, all my soccer bets are at betdaq which offer lower commissions on Asian Handicaps and have the same or even higher odds than Betfair. Please note that Matchbook can have this too if they wanted.
