DOTA2 announcement, the biggest Gameinformer ever had.
They had to triple their capacity just to handle the demand (over 300 000 views in a few hours, 375k as I'm writing this). Can check it out in the first informative discussion of DotA by a member of the press ever! Over 40 mins of talk about DotA and DOTA2.
A funny thing he mentioned is that with DOTA2's playtesting there's a 50 min cooldown period after each game where they not allowed to talk about the match at all. To calm tempers down and let the playtesters reflect properly I assume?
