If you look at the global stats page, you'll see that a payout occurred at around 3 AM, but not all miners have apparently been paid! Why paying some and not others instead of making it proportional since we are all waiting since yesterday? Anyway, it's not fairplay!!!
Just a guess, but I bet the larger miners got paid, although this wasn't intentional. Looks like a bunch of coins got exchanged at the same time as cryptsy finally sent the bitcoin payment, payment went out, but because there was so much exchanged balance sitting on cryptsy, there wasn't enough to pay everyone. I highly doubt this was intentional - payout script probably ran and cleared people's balances until there was no BTC left.
Anyway, it really shouldn't matter - everyone will get paid tomorrow, and then you can just smile about a much bigger then average 1-time payout.
I'm pretty sure payouts are still being done manually.
Also, if it was done according to the miner list, which lists miners only by the largest worker, not total hashrate, that could explain things, though I don't think it makes much sense.
