You want to decentralise where bitcoin is traded? It's dead simple.
Create your own exchange that has buy/sell fees of less than 0.25%. Mt gox starts at 0.6% and slowly goes down with bigger trading volume (for the average 50 BTC day trader it goes down to about 0.4%)
If day traders were aware of an exchange that charges less than MT GOX, many would flock!
How about NO fees? I had no idea that Mt Gox charged six percent. Even Paypal charges less, if I remember right.
Dude... c'mon... 6% != 0.6% and MtGox charges 0.6%
