Does anybody have any idea why the games on Full Tilt and Stars are so much tighter than sites like UB? I always figured that if a site has more players, there would be more bad players (by proportion). On UB, you find many limit games with high pot sizes and 30%-40% players seeing the flop in FR, while at stars the pots are small with 15%-25% players/flop. Do bad players simply find their way to less advertised sites? This doesn't make much sense to me.
