I often click to acknowledge a comment, not always necessarily because I "like" a post or reply.
The points system here has a purpose which works so well it's hardly noticeable to me anyway.

I click when I like something.

I click when I agree with something.

I click when I want to acknowledge to my fellow human being that his thought or feeling was heard.

I click to say "thanks" for taking the time to respond to me (or somebody else) - regardless of whether I agree with the comment.

I NEVER go on a click fest for points. That's utterly silly to me. I'm starting to wonder what everbody's obsession is with the points system. I guess, like most of us, everybody will finally get to a point that the level is an afterthought -- a thing for the "fun and games" category.

It really is not meant to be a contest. Really.

I will at times click them all, I read each one and consider my click their reward for contributing, long as they have done it without pissing me off they get a like... as far as points go, remember the post you like is getting points as well, never has upset me to get more people acknowledge my post, like a nod that we have that in-common, it’s how we build a community.

The lowest common denominator

I click "like" when someone has replied to a comment to show I have read it, or on a post that I like or believe was well thought out even if I don't agree with it, but do not have a comment to make. This amounts to many in a day.

Where is the " who has time to count the likes by any one person?"

I typically like any post I open and read to acknowledge that I read it.
I like replies to my comments for the same reason and I have upon occasion liked every comment made on a post I created.

I really do not care how many times someone clicks like

I just want a Goddamn t-shirt! ?

I think it’s subjective, that combined with whatever else they’re doing on here.
