As for the simple questions, I like seeing them on here. Most people know the answers on here but sometimes they generate great conversation about the basics and many times end up in disagreements on subjects we all thought we knew. I've been surprised before that's for sure.
I don't know if your a subscriber to the ecw magazine but they always have a q&a section about code basics. This magazine has been around forever and many times have in depth technical articles, but they still keep the code basics section, there is a reason for it. Like I said, the same question the OP asked is actually in the magazine this month so I think his question is valid.
