I've been trying this a lot, actually, since I've rejoined Dreamwidth, and it's been nice!! I'm also gonna use this space to just talk a little about how important fandom friendships have been in my life. Outside the internet, I cosplay and go to cons, and most of the close friends I have now are people I met because I went out of my way to meet new people while at cons. Hell, I met my wife through a friend I made at a con, and if that doesn't show how important meeting new people can be, I dunno what does!
Online, I actually tend to be a little more nervous about talking to people, but in the past few years I've really put forth the effort to meet new friends through fandom. And I've gotten some fantastic experiences out of it :D
