M.holsonWhy do you add people as friends?
Add people with orange names as friends. It makes you cool and you'll be in with the pros.
but seriously, Karma points is just a way to quantify how much you mean to the website. It's based on how others rate you and your contributions and how well people received those. The list of people online is just there because it can be, your friends will pop up above that. That's really the only purpose to the friend system on NS, you just see when they're online.
This thread will help you a lot with your other questions.
