...whom I've met in person: None. I've mailed snail mail packages to at least three of you, though, does that count for anything?
...whom I've met in person more than once: See above.
...whose house I've been to: None.
...whom I met/got to know through LiveJournal: I knew about 20 of you from elsewhere, and was personally responsible for recruiting at least 15 of you to LiveJournal. So the other approximately 95 of you are people I met through LiveJournal.
...whose precise geographic location I know offhand: How precise? I know countries for almost everyone and states/provinces for most. I know specific cities for around half of you, but for many people who I don't know the cities of, the cities don't seem very relevant. It doesn't mean a thing to me, for example, to remember which specific city in Norway Kasper lives in, because I don't know the slightest thing about any Norwegian cities.
...whose full names I know offhand: Somewhere around 25, I think.
Arsenothelys, Asrai_d, Butterickcole, Dlfke, Embryomystic, Frankepi, Inkstained, Jodawi, Jonesyak, Lalenalefay, Legolastn, Lentrot, Magpiegeese, Moistgrrluk, Princesswitch, Rachelkb, Roguebear, Roxann_Ireland, Slanderous, Technodyke, Whythingsburn, xk8tx . . . probably several others if I thought harder about it. But actually, if you want the middle names too, then I only know Embryomystic's, Frankepi's and Jodawi's. Though I've been told Roguebear's. Maybe I should have committed it more firmly to memory. Oh, and I remember Whadda's first and middle names, but her last name has slipped my mind at the moment. I'll probably remember later.
...whom I've followed/been in touch with for more than 3 years: None, but there at least five of you I've known for over two years, and some are rapidly approaching three years.
...who live outside my country: 22, I think.
