I've friended a whole bunch of people I know slightly. Some through Support, some because they've friended me / and or comment on my posts, some people I've met briefly at parties, some because we have mutual friends and LJ is good at creating connections. My flist feels a little unwieldly at 125; 80 to 100 seems optimal to me personally. But then again, I don't have much I need to do at the moment, and meeting new cool people seems like a good use of my spare time.
So, hi new people. Have some virtual tea (or other virtual beverage if you're one of those tea-hating perverts). Welcome.
I may end up removing people again if I feel like I have too much to read or nothing much in common with some people. And when I get a job I will very likely need to trim my flist quite a lot. So don't take it personally if I unfriend you at some point; it's not a character judgement, just that, well, there's a point where socializing can become a chore rather than fun, and that applies in the virtual sphere too. I don't want to get to that point.
And meanwhile, here is a comment thread for people to introduce themselves (to the rest of the friendslist, if as in many cases I already know who you are). Or ask me a question or two if you want to know something about me. There are no bad questions on this journal, though I might have to be careful about answering if the answer affects other people.
Of course, there's no prohibition on old friends taking part as well, if you feel like it! I'm planning to do another round of the matchmaking game sometime soon, but now that my friends list is scarily huge, it may take a while.
