Is their site written in c/c++? (it's on the list of requirements for the dev position at the bottom).
Maybe they're using it as a filter for smart developers. There's a lot of shitty scripty developers out there, but if you can show you know C you're pretty much guaranteed to be at least decent.
But then again, it might be written in C++; some very very large sites are. For example, OkCupid.
One has to assume this means that they might finally be updating their UI.
