He can be rude to people, but he understands C x100 better than anyone else in that channel, is obviously the smartest, and when he is actually around he usually does a faster & more thorough job of assessing someone's problem than anybody else.
And much of the time he's an asshole because the person he is talking to is dumb as hell. It can be pretty funny when somebody comes in there with a question like "how i maed game in C???" (and they aren't trolling but really are too fucking stupid to figure anything out on their own -- we've had threads by such people on /prog/ before I'm sure)
tldr; ask intelligent questions and you'll be fine
