I just hit this button looking for something and people have said nice things in there. I never knew they write comments about you. They all were kind. thanks to all for your remarks. People say nice things one should know about it. Would you say I am slow?
That is your karma. When you post something that someone thinks is exceptionally helpful or nice or they just like what you said, they hit you with the karma. You can see what they gave it to you for by clicking on the post name right before their comments.
