I am with you on the karma being about the same as a reply notification for me, but then I don't care how many likes my holiday photos gets on Facebook. I know people for who these systems has quite the negative impact. Below are two examples from Facebook. Example 1: Someone gets really depressed if they don't get about 10+ likes on photos on Facebook. Positive comments are ignored in favor of the number of likes. Example 2: Someone got really upset and depressed that only a few people wished them a happy birthday on their Facebook wall. Everyone else had done it either in person or via private chat, yet they went down the "no one cares about me" rabbit hole.
