Very different.
At my old school, I got along with the majority of people and was kinda popular but only made one REALLY close friend. (I know her since age five.) You know, the kind of friend you're inseparable from and can talk to about anything, and trust 100%? We're still in contact though she's studying in another city. She's very talkative and has interests totally different from mine, so it surprised other people a lot that we were friends. Still, I like her. She has exactly my sense of humor, and in some situations, when talked to, we're saying the same thing at the exactly same time, like twins or something. Which is amusing because we're very different personalities.
At university, the people I hang out with have obviously interests similar to mine. Duh. We're all interested in science so there's some common ground. I get along with them well and we're eating lunch together and go shopping as a group and such. Whether anyone is a "friend for life", I can't tell yet, I don't know them long enough for that. (It always takes me several years to connect to other people and get really close to them. Unfortunately. I guess they deserve better, as they're all very nice and I suppose I SHOULD consider them real friends. They probably consider me as one.)
Same for my chess club - it's easy to talk to them since there's a common interest and I'm respected both as a player and as a (rather successful) voluntary teacher.
At my art club (which was actually only an online club first, but in my city we have regular meetings and there's SOME interesting event every weekend and I've been going to events in other towns as well), I made some very close friends I'm meeting regularly and a lot of casual acquaintances. It's been helping me a lot to practice social situations.
Actually, I tend to get along better with extroverted and very direct people. Since I'm really, really bad at nonverbal stuff, it helps when people are SAYING what they're thinking. If someone is quiet, I can't communicate with them. I wouldn't know whether they're interested in a conversation at all.
(Maybe I should mention I'm rather extroverted myself.)
I rarely get along with the "geeky" sort of person.
