I know that I do not post often enough, but I do comment on other peoples posts, and I get very little engagement for my efforts on Facebook, now Instagram and Pinterest are totally different. You post a new image and you often get instant engagement. I have bought traffic from Facebook and except for stats, you get nothing else unless someone bought from you. All the others that clicked they become a stat, no username, no email, no ip address, nothing. For me, that's like getting half a coin. Now add a pixel to your blog, make a post and it's a whole new ballgame. Great post - I enjoyed it much
