Though it's awesome that people that are looking for people to play with and be "friends with" I'd just like to state that there really is no need to make all of these blog posts just because day[9] said so. You see there's already an awesome thread about this very subject where they've collected players of all different skill levels and put them in to a sort of database so that you can find new friends (practice partners).

There's the thread. I am not saying that you can't do posts like this because I have no authority over teamliquid. But I think that's you'll find this thread quite useful for the finding people purpose. Ah well that's all I guess. Good look finding someone to play with!
Or if just having practice partners isn't sufficient to your needs you can always make a thread like that and make your own data base for finding friends.
