Agreed - as long as quality/depth is of critical importance.
A trivial fee ($2) does not warrant such response and neither do we guarantee that.
However, by charging that trivial fee, the goal is to "guarantee" an answer to anyone. In sites like Reddit, unless you can pique some corners of one's brain, you are not likely to get an insightful response in a private setting. We allow you to 'own' your advice and women understand that it is only seen by you and not the whole community. Therefore, they tend to have a more 'personalized' approach.
Of about 65 questions asked and a few hundred responses received so far we have noticed that women are actually taking the time to respond. It's not the $1 they make, but the trend seems to be that they actually 'enjoy' providing advice to men.
