I often use the star at the bottom left of posts to add to the poster's reputation when I agree with what they said and feel that me "me too" post would be a waste of space. But I wonder what the point of it is.
Does the person whose reputation I'm increasing get notified?
What do they do with their reputation score - how does it help them?
Should I continue doing this?
Sorry if this has been explained somewhere else; I did search for reputation and found nothing enlightening.
