He was a character, that's about the best way to describe him. He was pretty rude, anti-Sox, huge Yankee homer, but for some reason there were a lot of people on the site who didn't hate his guts, that reason being that he was a pretty cool dude off the site. Still a ass either way you slice it, but he wasn't putting on the Gom Troll Show whenever you talked to him on AIM. His best redeeming quality was that he was as good at taking the harassment and trolling as he could dish it out. He was from Egypt, and lots of cabbie jokes were used on him, which he would play along with to the point that it was hard to tell if he was or wasn't actually a cabbie sometimes.
Also, he submitted a screenshot once that he accidentally (probably) forgot to close his porn in his browser, so there was a tab for YouPorn open, which he never lived down. (It was a screenshot of I think Matt Holliday's hot/cold zones or something like that, I'd have to re-check, but it was pretty funny).
But yeah, lots of people remember him for being inflammatory and irrational.
