I primarily join on people on my A list and then B list. Then it's joining randomly on someone on my friends list or publics. I don't mind people on my friends list joining on me though and that's how many people got on my A or B list.

[spoiler]C list is reserved for people in certain other community. I wish there were more groups and people could be in multiple groups at the same time so I could more efficiently pidgeonhole them.[/spoiler]
