A lot of LISPers roll their own software to scratch their itch and particularly in Common LISP that adds to the feeling of an insular language not useful for everyday programming. While it’s true you are capable of writing a HTTP server it doesn’t mean you ought to deflect from dropping awesomeness of some other kind on the wider world. However some kind souls do write software that for others and there is one particular library that you should get into if your bag is Common LISP. That’s lisp library is Quicklisp, which is actually a collection of lisp libraries.
This post was inspired by a post from Peter Siebel that I can’t seem to find anymore. Well, whatever happened there, I think it’s a great idea. So much so I pimped it at MXUG :) If you’re going beyond your first LISP book and you want to get into LISP properly check out Quicklisp. I think you’ll be glad you did.
