I started the thread more in the angle, if there is any significant profit for the gambling site owners at this stage if bitcoin economy. Or it's mostly for fun.
In the spirit of transparency and honesty some of them want to set, i'm sure a lot of people will appreciate if they share their profits or at least give us idea about them.
Drugs are the biggest market driver so far, it's logical to expect gambling will be next. But I don't think that's the case here.
(If you could order hookers with bitcoins that would be second)
Your problem seems to be more laziness than anything. Dooglus for instance has done a pretty good job of following the take of the biggest bitcoin gambling site, it's somewhere in the neighborhood of 15k BTC ahead at the moment. You can actually share in those profits too, by buying its shares.
More generally, every time some BTC game advertises as "provably fair" what it means is that you can just traverse the chain and establish for yourself, with 8 digit precision, how much it made.
In any case drugs aren't the biggest market driver. Repeating that nonsense is quickly becoming the Bitcoin equivalent of "God created the world": something stupid people say because they've heard other stupid people say it.
