I like the idea, but it seems some people are already missing the point of it.

Think of it like Facebook, you can comment and you can like. Usually Facebook conversations end with a comment with a thumbs up because the person can't be bothered to carry on responding. Here, it would be the person wants to express their agreement towards the post, but doesn't feel a new post saying they agree would be necessary.

The 'liked' post may give a point a poll never had, meaning they're two separately different systems.

+1 from me.

EDIT: Obviously, there does not have to be a poll in the thread. Someone could simply like a good/funny/detailed post.
