Someone close to me met their husband online. They talked on the internet, then eventually started writing letters and talking on the phone. Soon he came to visit then he moved out here (St.Louis) from Maryland, and they dated for four years before getting married last year.
Last fall I met somone in my area, from another message board. He was very normal and intelligent. We hit it off real well, but sadly he moved back to Wisconsin recently.
Not everyone on the internet is a psycho. You just have to be very cautious, and pick and choose who you meet carefully.
