Would you pay—real money, not credits—for a good answer?
Disintermediation… the real question is whether or not Quora is disintermediating consulting. Solutions… solutions solve problems. Gamification… could Quora credits be a version of neo-scrip [1]? It would be nice if Quora credits could be donated to support some charity of one’s choice, at least contributing towards a solution for someone.
I’m not at all convinced that you could buy the kind of really good answers one gets on Quora, as if serendipitously. Nor am I convinced that unanswerable Quora questions could even be answered satisfactorily for money.
