I actually feel similar to you, but probably in a bit different way. There are times when I feel like the comments on a post go on much longer than they need to. I feel like sometimes after a post and a couple of comments things are pretty wrapped up for me, but then the other person keeps commenting. I don't fault them, but I just don't have the energy to keep going.
I get that sometimes also. I don't mind if the discussion is valuable, but then sometimes, It is just reiterating what has already been said in the comment prior. Same with commenting on the post itself. Add value, don't only reframe. I get doing it for understanding though.
Yes, I've experienced that too and I totally agree with you
