It was like Task said, we are naturally rewarded with positive votes and in my opinion it is already a good reason to come and participate.

It may seem "little" to some at first, but if you accumulate these votes by commenting a lot, it will be very worthwhile.

In addition to Task, I and other users tend to vote on comments. Of course, unfortunately, we cannot vote for all 400 fellow members because of the VP, so that we are not less than 80%, but we try to do our best to bring the necessary motivation to everyone here.
