i've met people off the internet a few times. I used to chat in local AIM chat rooms, and met some one in real life a while later.
my biggest thing, was i flew to Canada to meet some one from a gaming forum. We chatted for about a year... And on the phone for months before i flew to meet him. My aunt was more terrified than i was, she even called the local police department to ask about him. He was from a small town, worked on the radio, and his father was a well known person. It worked out great... Except i don't suggest a native floridian go to northern canada in the dead of winter.
I also used craig's list to find a room-mate. She was coming on the college program, but had two cats so she couldn't be in disney housing. I was desperate at that point to find some one so we could get our own place again. And well it's worked out nicely.
i have a strange belief in, if it was meant to be it will happen, no matter what precautions you take. Like if a theif really wanted to break into your car, it'd only take him two seconds to jimmy it. Doesn't matter if you lock your doors.
What makes a person different online than a random stranger on the street??
