Met my great girlfriend on Myspace actually. Tried a couple other things, but they were far to formal for my style. (As formal as Internet dating could be I suppose)
On Myspace, I just e-mailed and talked to various people with interesting profiles.
The actual intro to how it all worked out was one of those survey things.
I wrote her and said that it looked like we'd end up on the same level of hell together, and maybe she'd want to get a coffee sometime if we ran into each other down there. After a few e-mails we decided to move the timeframe up.
