Comments are great but when people are mass commenting just for the sake of it, it can be annoying and time consuming to reply to. Wouldn't a charge for every following and comment be a good thing. I'm talking about a very small charge maybe 0.001 per comment & follow or less. Surely it wouldn't dramatically slow down all those that do mass following & commenting. Having said that I think more genuine comments & following would make steemit a better place.
I cant imagine these people get much return for their effort.
It would be interesting to see how many comments are "follow me" comments. I am going to post a "Follow Me Index" for Steemit later today.
