Just this morning I was checking out people who commented on my first posts 19 months ago and most of them have disappeared - around the middle of last year seems to be a popular time to disappear.
I am obsessed with Steemit and look at it every day - and I'm also obsessed with cryto currencies - but it all takes time to keep up with.
People who do a post or more a day usually burn out after a while - I do about one a week, and although I could easily come up with at least one a day, it would wear me out to actually do them all - and commenting is probably more important too but again, it all takes time.
