I haven't been on OkCupid in a long time. I think they first started publishing these data mining studies in maybe 2006? A lot of the old blog posts were purged after the Match purchase. I'm sure someone saved them off or they might still be on the wayback archive, but I don't even remember what the url for the blog was at this point and I doubt it's still even public. Your best bet at this point is probably just to read Dataclysm, the book Rudder ended up writing about all of his findings.
