Motivation

Just for the bragging rights really.

Seriously? Doesn't make a lot of sense to me why one would go for the 1st place then. It should be all about who get the most points and not who is engaging the most.
I mean, more points = quality engagement... right?

The point is more engagement, and points are given for engagement amount not necessarily quality otherwise I’d be at the top.

After a certain amount of comments, then comments does not give points anymore, but they still count towards the activity amount, which is the determinating factor for who is at first place. I just don't really agree with that.

I don’t agree with it either.
