Obviously noone takes tradehill very seriously.
What do you base this on? Tradehill doesn't have the top volume (Mt.Gox still has that), but it is solidly in the #2 spot. Clearly someone is taking them seriously.
yes, but that #2 position is not a close 2nd, but with 1/6th the volume.
granted, it is growing, but it's not a major force yet really.
all other exchanges combined are about 1/3rd the volume of mtgox.
