Ace: I think what many people are forgetting is that the 'fanboys', for a lack of better terms, of respective games are the ones who like creating long winded pointless posts under Yahtzee's videos and/or extra's. So ironically enough, when Yahtzee 'stops' so will the the number of people who have an IQ lower then a Gerbil humping a Rat on Coffee, and those are the ones who visit this site more often then anyone else, say as opposed to the more mature people who don't make dead baby jokes. So in both cases we win...or lose...pending on your definition of winning.
Angel: Many people already visit once a week at best to watch Yahtzee rant and write his Extra's. So I don't see how this is will affect that site that much, unless the aforementioned fanboys who visit every hour to...umm...you know, start a flame war.
Luigi: Although, Yahtzee brings in loads of new users and/or keeps them coming back. I and a few buddies of mine would never have discovered a few of the other stuff on the Escapist if it wasn't for Yahtzee...controversy is the father of all curiosity.
