In case you didn't hear, Team Fortress 2, a fantastic game in its own right, is now also free to play, forever. How is it financed? Mainly by hats. Lots of hats. Go download it and embrace your inner haberdasher (if you feel like it).
Will Jay Mohr be at BlizzCon again this year? If so why do people continue to have him host stuff?
We haven't heard anything about it yet, but it's safe to assume he's returning. Jay Mohr is a comedian who does better when he's off-script, so sometimes the obviously-scripted stuff he does at BlizzCon can be a little awkward or unfunny, but once he actually gets to make fun of nerds, he shines. A lot of people are uncomfortable having their idiosyncracies or the idiosyncracies of their particular subculture brought to light, especially in a "comfortable" environment like BlizzCon, but that's comedy.
What Mohr really has on his side, though, is the fact that he legitimately enjoys hosting BlizzCon. You can't say the same for every celebrity paid to host an event for nerds. In fact, you can hardly say that for any of them.
