It's funny, just earlier today I was thinking how useful something like this would be. Even as an experienced developer, there are times when I'd like to bounce ideas off someone else for more immediate feedback.

Right now, I do that with co-workers, friends, and peers working on similar open source projects as myself. People are often busy, and time zones often don't match up.

$10 for 15 minutes seems to be on the high end of what I'd be willing to spend and really on the low end of what I'd be willing to charge. I'll probably give it a shot, but I feel like there needs to be more incentive to be a mentor (whether that be monetary or other).
