I do not know. I do not count.
I do not care either.
And it does not even matter either (on a properly working social network).
I write a comment, when I have something to say/ask.
I use the platform naturally.
There was a time in the past, when I commented a lot, and I was on the leaderboard.
There was no difference in that case either.
And a properly working social network is not a contest, not a challenge anyway.
On Facebook, no one asks how many comments do you make on other people's posts.
They use the platform naturally.
They are there actually for the content.
Even in the smallest Facebook groups (for example a few hundred members).
They actually really care.
Even if you do not write a comment under other people's posts at all.
