Bitcointalk Traffic Stats

also bitcointalk.org is earning $2,068,560 ~ 48.63 ~ BTC per year

That would be correct or ~ if bitcointalk was monetizing the forum with google ads. Since most of the visitors are from countries where CPC is quite higher, the estimated amount isn't too bad.
edit-

That's not the case: the last auction for 29 days of advertising produced 0.036BTC.

That's too low. I thought forum ads revenue was quite high as I didn't check closely ever. I was in the wrong thought that forum generates at least 0.10 BTC in an auction.

And if we trust these websites then bitcointalk.org is worth almost $42.87 million ~ 1007.93 BTC

Slightly more if you count the Bitcoins owned by the forum.

That's their estimate if advertising would be maximized. That's not the case: the last auction for 29 days of advertising produced 0.036BTC.
