I'm guessing that pg wrote it to use lists, but it turned out too slow (he has a site to run using arc), so he's using regular strings for the time being. The first thing you do when writing programs in a language like Haskell that munge large amounts of text, for instance, is to stop using the built-in strings-as-lists and switch to some sensible library like ByteString.
