Basically the only benefit I can see is that it allows you to locate certain people faster in order to send messages or check their gallery... kind of like bookmarking them for easy access to their homepage and gallery and site mail.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
