Credit system added to Quora

So apparently a new credit system has been added to Quora, where you can ask specific people to answer your question. If they answer they earn credits, which they can then use. Or at least that is the rough and simple explanation of the system.

You can earn more credits in a few ways.

Answering Ask to Answer requests: You'll receive credits for answering ask-to-answer requests (an amount equal to the number of credits it takes to send you the request).

Getting upvotes on answers you've written: You'll get credits for any new upvotes on any answer or post you've written on Quora.

Soliciting an answer (via Ask to Answer request) that receives upvotes: Any upvote on a answer you've requested will get you credits.

Credits given to you by other users: Users can give credits to each other whenever they want.

Occasional system refreshes: We'll provide credit refreshes if you go for a while without enough credits to ask the average priced user.
