What Is A Nod?

What is a nod?

I can see sometimes on my activity page that a comment I made received 1 "nod" and I assume that means someone else agreed with what I said.

However, how does one give a nod to another?

Is that the right idea?

Thanks!

A "nod" means someone "liked" your comment. So when you click "like" or "rate up" on someone else's comment, they receive a "nod".
