I like giving (and getting) thank you messages for the Karma. I try to leave a note to tell them why I am giving it and I especially like the notes people send to me when they give me Karma. It's just a nice "warm fuzzy" to show that their (and your) time in making comments is appreciated.

It's those little notes that come with the Karma that I like the best!
There can NEVER be too many "warm fuzzies" in the world.
