He doesn't say his site will limit itself to mentoring about business.

As for evaluating mentees: that's a good question. I guess it's not very different from selecting any other type of associates (employees, cofounders), just the stakes are not so high: it's less traumatic to terminate a mentoring relationship if things go wrong. There is no money at stake, and any time investments have supposedly paid for themselves until not long before it became clear it was not working out.

The standard solution to hiring (written application, followed up with interview) should be a good start.

I did not even say I want to solve this problem with a web site. But I saw the same problems you pointed out.

For example making the service expensive would weed out a lot of people who are not serious about it. But I do not believe high price this would actually be a solution.

Perhaps matching mentees and mentors is not that different from matchmaking in a romantical sense. We could learn some things from dating sites.
