This is a bit off-topic, but that "DT power" is something that tends to get very exaggerated in the minds of those who aren't on DT.  If I don't agree with someone--or they lay into me with a barrage of insults or what have you--I can't just leave them a neg for doing that, which is why I haven't tagged trolls like cryptohunter, digaran, and all the other ones who've attacked me.  If they've done something untrustworthy on top of that, then tagging them is definitely indicated.  Other than that, it's more of a responsibility than some intoxicating feeling of power, and ultimately all the power means is that a DT member's feedback carries more weight than a non-DT member's.

I never got the impression that Theymos was a power-tripper.  He mostly stays silent and lets the forum work things out on its own, and he only makes small (but sometimes significant) changes here and there.  That certainly doesn't meet my mental picture of what a power hungry person looks like.  If that were the case, I'd expect to see a lot more censorship and more of his presence at the very least.
