No, reddit nor twitter pay for posting, nor does FB for that matter, but I have over 1400 friends and followers there. I've been doing the "Suckabug two step" since about 2003 (Suckabug = Zuckerberg, the idiot who founded FB and can't afford a decent haircut)
So I just can't turn my back over there. As much as I hate it, I know when I've received a PM, (private message) I can see my newsfeed (if I want, now steemit has done away with the newsfeed) etc etc... my brothers and sisters and most of my friends could never POSSIBLY hope to navigate through the madness that steemit and the other front ends have become.
