I suspect the hard part would be finding people to pay to get their questions answered. Sure I could spend £10 and ask a bunch of random people "Do you like cake?", but without more detail such questions will be simplistic. If the answerers are being paid to respond it's only a matter of time until they get replaced by bots. I'd spend a few hours writing something to scrape an email, SMS, or web-page and just reply "yes, yes, no, no, yes, yes" if I was going to earn money from it. In short it's a cute idea, a kind of crowd-sourced yahoo-answers, but "Yes/No" feels like too easy a reply. Forcing users to respond "properly" with actual detail doesn't help much either, if you get a question like "Why is the sky blue?". 50% of people will copy&paste from wikipedia, 25% of the people will think "That's too hard, I'll wait for another question", and the remaining 25% will say "God", "It just is", or "The answer doesn't matter, if it weren't blue you'd just ask why is it red". In short: * Simple questions are too simple. * Complex questions will probably go to the wrong people, but they'll reply anyway to earn their money. * You need to be able to "Judge" answerers on different metrics to stop bots. * I suspect many answers would benefit from direct conversation between poster and replier; for example you might say "Your answer was interesting, but why did you say XX?" (i.e. Allow answers to be interactively refined.)
