Anything I've missed? Which one do you identify with? The professor These are among the most knowledgeable posters on the forum. They rarely start any threads, but the love answering them. But when anybody corrects them, all hell breaks loose on the thread! The politician These love to argue in the politics section. They rarely post outside it though. If you post anything remotely political, you must have ran into them. The social birds These love talking about nothing and everything in the general discussion section. Everybody loves them. The administrator They tend to keep low and only appear when they are called. Simply typing @Greg Bernhardt summons them. The over-ambitious student They are often too ambitious for their knowledge. You recognize them by threads asking for help on problems in Jackson while they are currently in a trig class. The crackpot They appear once in a while, but aren't as numerous here as they once were. The administrators keep them out. The confused student The more you help them, the more they get confused. Can lash out when they aren't helped in 10 minutes time. The science amateur They're interested in science, and love to read up on new things. But they lack the will to study it formally. The lurker Just reads. Never talks. The good student Asks for help in a nice way. Threads are always very structured and informative. People love helping them. They are a rare breed. The lazy student Don't bother to learn LaTeX. Posts pictures with vague unreadable handwriting (and often the pictures are upside down). Expects to get the full solution quickly. Often doesn't reply again.
