Why be politically correct, Stack Overflow is the top Q&A site for programmers as of present. And members answer questions just for the love & passion of knowledge without any expectation as such. But do the owners of SO give any monetary incentives to the top contributors, like those who have 100k+ reputation and provide the bulk of the answers, the backbone of the site? And of course, the name and goodwill from more than a million users around the world is a tremendous motivation. But still, what if a competing site crops up in future that offers monetary rewards to the contributors who pass a criteria?
Contributing for passion and interest is fine, but then people have time constraints due to which they may not be able to devote the time they wish to. So it would be great if they get a monetary incentive as well so that many contributors won't think twice about devoting as much time they want to the SO community.
Do such incentives exist? Any in the offing? If not why?
BTW what is the turnover of Stack Exchange?
