The majority of posts seem to have very few comments or meaningful feedback. There are a lot of exceptions but that's because it's honed in on something that you get rewarded to answer or are passionate about. There are some people who tend to generate "buzz" or put in some time to chat and relay information and opinions in the comments section. In fact, the comments section is where a lot of the real grit and dirt and who likes who comes out for all to gaze upon. It could be argued that for a lot of posts and users that the amount of comments tends to directly tie into how they are perceived on the platform.
This is par for the course because your stake is used how YOU see fit no matter what pressure is applied, it is all on you baby! Human nature itself lends to circle jerking so it doesn't take an Einstein to figure out that people support who they click with. Lots of low payout posts ask for opinions but nobody seems to answer and that may be just for show or maybe it's boring to the reader so they are not engaged.
If someone is supporting you or interacting and you never reciprocate then I see time and again that those rewards will dry up because nobody wants to feel like they are a piggy bank. I have gone out of my way for some to not even have so much as a comment left or anything so why will others bother with someone who "plops and drops" posts across platforms. Look at my blog and look at the amount of interaction and comments to see how it's done. 
IMHO, a healthy Ecosystem has plenty of both buying and selling. That's how trade is done and not everyone will HODL and some will only HODL. That too helps stabilize "The Force" of a tribe. If you see something doing better look at male to female ratios, look at diversity of the userbase and the tribes within the tribes. Maybe just maybe getting out of your comfort zone or clique will make us higher than yet another actfit token. ;) OP/ED only ...I have no beef with actfit , clearly they are doing A-Okay.
