I've never really thought about diving deeper into those tools until you and several others have been mentioning it more and more.

Quora has surprised me how much traffic you can get from it if you're correctly and directly answering questions with value

I highly recommend Quora as a marketing channel. It's worth exploring for your subject. Some areas aren't great, but some are very good. Mine (interviewing, salary negotiations) is particularly good on Quora because people have LOTS of questions about those things.

You could just search for a few terms in your area of expertise and see what comes up. You'll know pretty quickly if there are a lot of questions about it, or if Quora might not work for you.
