I personally believe that the level of competition has increased steadily. Since I've been here, I've seen many new players who have raised the bar such as Cach, sly, Tasnica, 8foldWay, CStein, ghug, gen. lee, fairfax, SD (gb only), and many others. I think that it might be harder to raise your GR substantially now than when the site was new. Not to start a flame war, but I don't know if the old upper echelon would have gained as much GR if they competed with the current crop.
@zultar: Among nerd accomplishments, you forgot their inspirational defeat of the Alpha Beta fraternity.
I was merely echoing your own "Ok, since I'm a big nerd" statement earlier in the thread. I agree with ghug that anyone playing diplomacy online probably qualifies as a nerd. On top of that, I read comics and sci fi, and play D&D, M:TG and bridge.
It was a nice rant though, and reminded me of "What have the Romans ever done for us?"
