Frankly I've only used Facebook to chat and to play a couple of games, I once opened an alternate account to try to advertise some opportunities, but after a while I decided to stop doing it, no results and in fact it was spamming. I do think Steemit is a better patform for actually debating something, and let's face it everybody likes the opportunity to make some extra cash just writing, even though up to now I haven't made much, but the opportunity is still there.
