ETMM is the killer right now. The other MMs have moved up to 0004 to let Etrade get rid of his shares. I suspect the others know what is about to come and don't want him in the way when the buys start coming in.
We did a rolling count at one point to see how many shares people had and it got up to 400 million. I assume it's gotten a bit higher since then. I know I have added a little over 9 million and will probably add more once I see Etard dwindle a bit.
