I disagree with the criticisms of Stack Overflow. First concerning the "game required to get a login and password" - the great thing about sites like SO that use OpenID is that you don't need (yet another) login/password to remember in addition to the hundreds you already have for other sites - you just click a button. I'm not sure how it gets more simple. Concerning the strict standards for posts, that is what makes SO a great resource - you don't need to spend time as you do on typical forums sifting through the garbage until you find something actually relevant and informative.
