Lots of good information. The part I liked the most though were the ideas related to the Stable Marriage Problem. OKCupid looks like it could provide a much better environment for finding the best match for yourself rather than just finding a decent or acceptable match. This is an area I haven't seen properly breached often enough.

Additionally, were there any specific resources you used to get better information on the basics of OKCupid culture and presentation when you started?
