The point is not to get anyone to be your "part time DBA" that was just some example question I came up with, hopefully to spark some kind of debate or just usage of the site. I am basically just giving someone $3 for their 2 cents on a scaling question. I think asking for someones opinion on scaling is a little different then asking them to be your part-time DBA.
About the financial incentives, the creator of the question can set the "Bounty" for whatever price they want. And if it is not worth someone's time to answer the question for that price then they can just ignore it right?
Really I am just trying to create an environment where people can offer "something" for help if they are not getting it elsewhere. It is not meant to be a source of employment but just a nice reward for someone willing to lend their time and knowledge.
I have a hand full of friends still in college who would pay a few dollars someone to walk them through a math proofs problem for example..
