I think it's that:
1) some of the questions are a bit obscure
2) some of the questions are compiler specific
3) some are so stupid that we know someone else will answer it, and we won't have to waste our time answering it. yes, I know it may seem harsh, but think about it: One of the newer board questions was somewhere along the lines of "How do I make an executable file using C++" only with more spelling/grammatical errors.
4) Some people ask the same questions over&over&over again, and or did absolutely no thinking/researching/testing before they posted.
The general board is just a fun place to blow some stam off and relax when you're on the internet and bored. We have a lil' community here, and I guess it's only natural that we want to talk about other things besides computers and code with eachother. makes sense to me!
