I used to add friends left and right and just talk to everyone about anything. Was fun, don't bother anymore. I've got like 2-3 people I talk to regularly, and we just talk about everything, literally lol. The rest just sit in my friends list, I haven't bothered cleaning it up.
I've become pretty busy outside of gag, I can answer questions during breaks, but I don't chat; it takes away too much from my concentration.
