My wife and I met online in 1992. Not on a dating site; we were both posting to a Usenet group, alt.psychology.personality. She had posted that she was trying to figure out whether she was a Five or a Six in the Enneagram system of personality analysis. My first words to her, in a private email, were "Well, do you have a bigger problem with depression or paranoia?" Ha! How's that for a smooth come-on line?? :-)
