"The answer network"

The site uses two kinds of currency. Real money for "pro" questions and "info credits" for "quick" questions. They like the concept of twoness. Every question gets two answers.

Every answer earns something. Quick questions cost 200 info credits and the two answerers each get 100. For pro questions the payout is also split, but weighted according to the rating the questioner gave the answer.

This site is easy to get into if you register and start spending the 600 info credits they gave you to start.

The questioner pays cash up front for the pro question and it's resubmitted until one of the two answers is satisfactory. Pro credits translate into cash paid out monthly if you have more than $10.00 worth. Info credits are used to buy answers.
