Wow! I met my wife just over 7 years ago there, and our 2nd kid is due in a few months. Hard to believe that the personals section is gone.
Met my first wife at college, the "old school" way. Met my current wife through OKCupid (after seeing another girl I was dating at the time using it).
I knew more about my second wife before I'd ever messaged her. Saves a lot of wasted effort simply basing the book on its cover.
