Isn't most of it going to BTCGuild?
I for one welcome our new hashing overlords.
About 40% to 45% of this does...
Meaning that over the course of a day there are 144 blocks to be solved.
144 * $5,248.35 = $755,762.40 a day.
BTCguild get's about 40% of that.
IE: They are making (collectively) $302,304.80 a day.
