I really enjoyed reading this. On the flip side (as an OKC user), I've also had moderate amounts of fun trying to figure out their algorithms by trial and error. For a while, I discovered I could figure out who scored me highly on their Quickmatch [1] feature by visiting it repeatedly - the ones who gave me a high score always came up first. This doesn't seem to work anymore. [1]: If you haven't used OKC, the idea is: you score potential matches 1-5. You can tell if someone scored you highly (but not who) and if both of you give each other 4 or 5 you get a message "introducing" you both. If you're an A-list (paid) member, you get to see who scored you highly without scoring them. Edit: tweaked phrasing as per comments.
