Nope, that's a misconfigured server, an error that only crops up when using multiple server without having sync'd some keys in the machine.config properly.
I got the same error on a few pages, but the site also (repeatedly and reproducibly) crashed my browser when I tried searching for a college.
I thought I would love the site after reading the article, but the actual execution kind of sucks...not just because of the programming errors, but because of the general site design and 'flow.'
