Good point, I still see a ton of questions on SO like, "How do I add two numbers in teh PHP?", which seem to get both upvoted and replied to a lot because hey it's easy karma. Chat is the perfect place for this kind of stuff, because a) most new programmers I would hazard don't know about IRC, b) you can help clarify a poorly or sparsely worded question quickly in chat and c) it will hopefully decrease the dross on the front page.
