I don't think guy has problem with drinking...Its about focus. And he is right, people go to these conference just 4 drinking and partying hard. Actual talks just get over shadowed with these booze parties. Its not "necessary" to make them part of culture...It should be optional. Come-on, most part of a 650$ conf ticket is for booze ...isn't it.. ? I think it should be like paid (and discounted..) "buy extra coupon" if u want to booze...
