Based on what I'd seen in question threads, it looked to me as though datatype/code/syntax questions were always popular, which a couple of you have confirmed here. It's perhaps because it's something we all have to deal with at some point or other, whereas questions on pure admin areas may seem irrelevant to developers and vice versa.

Personally, I just like a question to be clear about what it's asking, rather than try and obfuscate its intention. My own questions are usually nothing to do with what I'm working on - in fact the last few have come directly as a result of other QotDs or the discussions that followed!
