coan.net: I'm not sure... if this was a threaded board, it might work, but on an open board such as we have here on BK, I think there's a risk of cluttering, expecially if some of those answers provide some good conversation, like you said... which, by the way, could also make this turn into a debate club (which is not necessarily a bad thing, but it's not something I'm prepared to moderate, that's all)
Also, I'd run out of questions preety fast if I were to have to come up with 5 different questions every week

Yet, I had already thought in the past of the concept of a quick interview, I just didn't come up with a right way to put it in practice... Somebody else care to comment on coan's idea?
