Either way, I suspect a lot of money exchanged hands in this deal. WoWhead.com sold for a reported $1 million and I would wager its traffic statistics were on par with MMO-Champion. I would be interested to get the details of the sale.
Fortunately, Curse isn't some scum-sucking company like ZAM (who purchased WoWHead). And all I know is that MMO websites are big business and I'm sad all the sites I've volunteered for and poured my sweat into over the years missed the money train.
