That's a great article. I'd thought mostly about Medium, because it seems like our style of content is a more direct competitor to them, but Quora is interesting. My partner is regularly a top answerer there, so I'm more familiar with it than I am with Medium. It might be nice to see a Quora-ish frontend for Steem. I'm down for answering random questions but it's not super-easy to find that sort of thing here.
