Umm... what? Obviously I am of camp 1. Whenever people start talking to me like this, I throw a hissy-fit until I know what's happening. On a similar note, I -really- hate private jokes, for this exact reason. Some would say it's selfish to keep the conversation on Rory-inclusive things (there I go!) but usually with my friends the case is, there are MORE than enough things that involve everybody to talk about. Besides, only losers dwell on the past. In conclusion, I agree that Thingdom is good for situations where everybody knows what's up. Also I use Dudedom, because referring to everyone as "dude" is much easier than remembering names.
