It is interesting that on this AMA you say both "ideas are worth so little" and "a really compelling idea is more important to us than traction or revenue." Can you elaborate?
I think the compatibility of those statements hinges on the difference between an idea in the sense of something you could transfer in an elevator, and an idea in the sense of the culmination of an entire viewpoint on a topic, along with the mind(s) that developed that viewpoint.
