I think we'll keep questions and tips separated.
If I'm a new guy and I have a specific question I need answered, it's much easier for me to post my question and wait for the answer instead of looking through dozens of existing questions, trying to see if someone already asked/answered my question.
Yeah, the new guy's question may have already been asked and answered previously, maybe more than once. But I think that no mater how many times a question gets asked, there will always be someone willing to jump in and answer it. And IMO, keeping the questions apart from the tips just makes things easier in the long run. Maybe it's a fine point, but I think it's valid.
