I'm sure the OkCupid folk are nice people but it was: 1) founded by mathematicians and an academic, and 2) written in C++, with a custom templating language Even giving them the benefit of the doubt that the core matching algorithm warranted C++, the whole site really shouldn't have been built that way. I'm really not surprised there's poor technical decision-making there.
