Is it possible to fall "in love" with someone you've never met?

I'm curious to know. A friend of mine says it's possible, but I'm not so inclined. After all, how do you know if the person on the other side of the letter, e-mail, webcam, chat room, etc., is telling the truth about themselves, or if they're even remotely close to whomever you perceive them to be. That's one reason why I'm not a believer in internet dating. The other would be is that I've tried it and got burned badly, very badly.
