I guess you weren't watching for the last few weeks when we averaged 1-2 BTC on Mintpal and .5BTC on Cryptsy for 24 hours day after day.
That's still pretty low, though. We have a lot to go. We need more liquidity in order to create a market.
BTW, is there any project in the works for an auction site?
This is a good idea, I've been pushing for this sort of thing for a while now, maybe somebody who knows to put one up is silently preparing one.
