I agree -- Mt. Gox is a mountain, Trade Hill is a hill.
A lot of people have money stuck up on the mountain, so even if they prefer Trade Hill now, they have to check it to the party tonight even if just for a little bit.
For all we know, people will get their money & BTC out en masse and then head over to Trade Hill to do their buying/selling.
I guess it depends on where the most money can be made -- it's all about the money for traders (what else would it be all about?)
I can always tell how bitcoin prices and difficulty are doing by the number of messages I get for my sales thread.. of course 90% are people who want to buy gear going for 500$ on ebay for 300$ worth of bitcoins, and me pay shipping to nova scotia. and then not getting paid until i ship the goods and they test it run it and overclock it and it runs fine for 2 weeks then maybe they pay me, etc.. etc.. ahhhh bitcoins.
