lol i've done this before. i talked with this guy, it was 4 yrs ago i guess when Encore dropped, he was like 'omg we should go n buy it together', so we did n it was like normal. 2nd time was when Curtain Call dropped and i talked with this guy who had a discount in a music store, so we went to buy it together too.
i also met one of my best friends in college through internet, she IMed me, because we both were going on this integration camp, and i was like the only person from our year there, so she wanted to be in the same room with me. it didn't work out with the room, but still, we met up there and she turned out to be an awesome girl.
we got this myspace-like thing here in Poland, it's called grono.net, you got your own profile and there are those small forums, music, sports n shit, each person can create one and people just join. every school, class, university can have few ones, i think it's useful because you can get to know the people who's gonna study with you. you can meet up and it ain't that awkward at the beginning anymore, because you already know each other.
and it turns out that alot of people met their partners on the internet, i was surprised to hear that at least 2 or 3 people from my workplace had/have relationships with people met on the internet.
