You've just made a friend in line. How do you prefer to exchange contact info?
Since there's SO many ways to exist in the interwebs, I was wondering if there was an informal PAX or forum consensus on the best way to quickly exchange contact info? "Best" could be quickest to access, easiest to find, etc.
Facebook, Twitter, Snapchat, Steam, XBL, PSN, whatever Nintendo is using now, the PA Forums...? Or is it easiest to just have a notepad and pen on you at all times?
