All the same, there is a great deal that I disliked about Experts Exchanged. Two complaints stand out:
1.) sometimes the other people on the site gave me excellent help, and some even put in an extraordinary amount of time to help me. And yet, they didn't get any money for their efforts. Experts Exchange kept 100% of the money that I paid. The people who answered questions just get meaningless "points". But clearly these experts deserve some money for their time.
2.) sometimes the other people on the site did not give me any help at all. In fact, sometimes some were rude, or they would only answer "RTFM", or they would fail to read my whole question and they would post an answer to what they thought I was asking, rather than what I was really asking. Again, this is a problem that would have vanished if I'd had an easy way to send money to the people trying to help me. People would take the time to answer my question if I was paying them to read my question.
I also thought it was disgusting that so many people put so much effort into helping each other and yet Experts Exchange keeps 100% of the money made off of those efforts. I've the same criticism of StackOverflow nowadays -- they keep 100% of the profits coming in from ads on their site, rather than share the money with the experts who answer questions.
My negative experiences with Experts Exchange were an influence when I created my own question and answer site ( http://www.wpquestions.com/ ). Here, 95% of the money goes to the people who answer the question, and the distribution of the money is decided by a community vote. I think a question and answer site has the right to charge some fee to pay its bills, but since the experts who answer questions are the one's doing most of the work, most of the money should go to them.
I applaud that you have created a site that tries to compensate the effort to its contributors... I just hope that you have managed to tailor the site to avoid the problems that money can bring.
> a better motivator than reputation
Nothing I wrote suggested that in any way. You are reading a message into my words that simply isn't there. Rather, just the opposite: the top experts on WPQuestions.com have often written to me and said that the reputation that they gained on WPQuestions.com is worth far more to them than the money. More so, when they talk about WPQuestions.com on their own personal sites, they do so to advertise the fact that they have public reputation that is established on WPQuestions.com. Consider what Denzel Chia, our top expert, say about us on his own site:
"This is where I answer questions and get paid! Most of my clients came from here!"
Clearly, his reputation on the site matters to him, it's not wholly a matter of the money that he earned, it's also he's proud of the work he did and he wants people to go and look at how knowledgeable he is.
Same with Ivaylo Draganov, who links to his profile on my site from his site: http://druuf.com/
Same with the others, the top experts who link to the site from their own sites, which several of them have: http://www.wpquestions.com/user/winners/order/desc/
I don't think money is more powerful than reputation as a motivator, but I do think the 2 of them together can be combined in powerful ways, perhaps so powerful that people sometimes find the implications unsettling.
I do understand what you mean when you write:
> I just hope that you have managed to tailor the site to avoid the problems that money can bring
That's why the money is distributed by a vote. So that people can give public recognition to what they think was a good answer. All votes on the site are public, so if you vote $10 to what you thought was a really good answer, everyone on the site sees that you are voting $10 to that answer. It's a form of applause: a way of saying "Well Done". But votes carry more weight when they are backed up with money, rather than just being votes for something like reputation points. Or rather, votes carry more weight when they impact real world events, as opposed to those situations where they only impact a system of relations that only exist on a single web site. There are a lot of systems of voting in the world, and some impact upon real world events. Basing voting on money on a site is a way of tying the voting on that site to concerns that are important in the wider world.
As to the overall amount paid, it has apparently worked out pretty well for a number of the top experts. I cover the details in this old video from November of 2010:
Also, I think you highly overrate how much SO makes from advertisements.
