First time around (going from .0001 to .0070) the MM controlled a large majority of the shares. It was in their best interest to let the pps run high and sell a large portion of them at higher levels.
This time around it seems the float is almost consumed, and we are just trading amongst ourselves until we get a nice piece of news. MM seem to be lining up at .0060, but when the market opens we have retail come in willing to sell their shares cheaper. I'd rather have US in control of the shares than the MM when the big run comes, because I know a very large portion of the shares we hold are not going to be sold cheaply :)
