One of the things I love about programming is that you are always learning new things. You have to learn new things to keep up.
Incidentally, over the course of the language stats project, I was surprised at how much helpful stuff Yahoo provides, first and foremost, a real API for their search engine, something that Google no longer has. Hopefully, it’s a sign of better things to come for them (if for no other reason than to keep Google on their toes!).
By the way, for those interested in the language stats project, I set up a forum with RSS feeds, where I will be posting updates, and accepting suggestions for further improvements.
