I don't think anyone is going to make much money off of it starting out since I don't have a large supply of questions coming in yet, but there are a lot of underemployed devs out there who would be happy to make an easy $15 bucks an hour just googling answers for people and telling them what to do.
I think a lot of poorly-received questions on S/O are the result of people not knowing where to look for their answer, or being intimidated by reading the docs or source code. So they post the questions hoping someone can guide them.
Call a Dev isn't a competitor to S/O. S/O is a wiki. Call a Dev is basically Clippy in human form that you pay per minute.
