Out of curiosity, is there an open source version of BuiltWith? I'm not necessarily looking to use it, but it might actually be an interesting project to work on. I'm sure you learn a lot of interesting things trying to map everything out..and then there's the parsing/extracting and other aspects of this that could be fun if you're into that sort of thing.
