Guh! Orbitz! Second to X10 in use of annoying popup ads on the Internet! I'm sure they're a good company and have good deals on flights and such, but those popup ads are the worst.

But I agree, no language is without merit... I've just never seen Lisp or Scheme used in anything except things like artificial intelligence/neural networking projects. It's very interesting to hear that your company is using them in the "real world." What are you using it for?
