The post is from last April. If I click on any hyperlink to the post made between last April and last week, I instead get redirected to OKCupid's blog homepage, which does not have the article. If removing the article "changed nothing", it would still be up. The idea was to make it harder for people to find the article. Sure, someone who realizes that the article was purposely removed and that there are a multitude of copies hosted on other sites will be able to find it, but others (perhaps with less technical acumen) will not.
