Howdy sir Farmer! I didn't know people weren't commenting as much, I can't keep up with my comments. But I have noticed that the actifit and steem monsters have let people really get lazy with their posts by just putting their actifit report up or a game results page up. I still see lots of challenges and contests though.
I don't see it as a problem if there is a lack of interaction, they'll pour back in when the price rises.
