Is it possible to fall in love with someone on the web and does it ever work out?

This question is requested by my daughter. Is it possible to fall in love with someone that you have never met in person? Is looking at a photograph and thier written word enough to bring two people together? And, do social websites really work or are they just another means of taking our money?
