Which usernames do you recognise?
danteembermage: This is top of the head so no promises on spelling. I remember cpercevia because he had a really great proof from a post your proofs challenge I did a while ago. edw519's comments seem to stick out for me about technical stuff. Byrneseyeview has delightfully provacative stuff, a little edgy but generally sensible and well thought out. RMS only for the whole getting kicked out thing, it was big enough at the time to stick with me. Nostrademons because I was interested in how his game-clay thing was going to work out. And logicholeflaw because we're old friends irl.So on the whole it seems like I notice on part expertise part random. I don't vote much though so I don't think name alone gets me to click that up arrow.
