Oh yeah, of the 67 people on my AIM list:

39 I know through the internet only, mostly from EoFF.
4 are family.
24 I know through school.

of the 39, I've only talked to 13.

of the 4, I've only talked to 1 (my brother).

of the 24, I've only talked to 16. Some are doubles (two SNs for the same person) that I haven't deleted, or that they still use.
