One issue is a red fish with no delegation and 0HP can make a total of like 3 comments before being out of RC.
Another thing is that most probably don't realise that comments can generate a decent amount of rewards assuming people actually upvote them. I personally upvote every comment I get that has decent substance in it and isn't something I disagree with.
The general narrative I hear when comments are mentioned is that they don't give very good rewards so you shouldn't bother with them. This is in regards to curation and voting which is a terrible narrative to sow. It can make people think that commented itself is a pointless endeavour when it comes to rewards.
Another factor is I see a lot of talk in general about how to posting and curated posts and how good it is but I see very little talk about commenting and upvoting comments etc.
Actually one thing I noticed is a lot of users, yourself included, only have paid out old posts. I don't mind posting on old post if it really catches my eye, then I usually tip. I'm not a stalker enough to check who comments where 😂
But yeah, my point is a lot of bigger accounts don't have active posts to interact with from what I've noticed.
That's what, people signing up here things that all post can generate more than $10 but they don't actually see how much a person has build his reputation as well as he is working for the community to get that amount. I remember when you create an account you get 15HP delegation, isn't it true now?
Not aways, some account creators do delegate but the 15hp was done by the steem it stake back on steem.
