Do you have any guarantees about how quickly a response will come in? I'm a bit concerned that the low payrate to the dev means that you're likely to miss higher skilled respondants. The payout isn't high enough to justify going FT on it and it feels like it'd be unreliable to try and pickup questions here and there when you happen to be available.
Thanks for the question! Your concern is justified. There are no guarantees. The only thing for certain is that if you don't get a ping within 60 minutes then your question will be deleted.
It's kind of a chicken/egg problem where there aren't enough questions because I don't have enough people to answer them, and there aren't enough enough people to answer them without a steady supply of questions to keep them busy.
I'm reconsidering the pay rate after reading a few of the comments here.
