For those of you interested in playing competitively, I suggest you check out ESEA at www.esportsea.com. Basically its $6 a month to be able to play in well run pugs. I know I enjoy it for source, and I know they recently introduced TF2 servers, but I'm not sure how those are. But if you want to get better, its definitely the place to be.

If you play dota (and I know you do) join the TJ Dota group on facebook.
