LispURL.com issues a LispURL for any real URL entered through the main page or the bookmarklet. From that moment on, whenever someone requests that LispURL, LispURL.com will redirect the request to the original URL entered.
For example, when, earlier, I submitted http://www.gnu.org/licenses/ on the main page, LispURL.com returned the LispURL http://lispurl.com/cddar, which from then on started to redirect requests to http://www.gnu.org/licenses/
One of the main practical appeals of URL redirection is that it makes URLs that are short enough to be used on Usenet, Twitter, in E-mail and SMS without getting wrapped around or exceeding a line length limit. (Line-wrapping of long URLs may render them virtually useless with some Usenet and e-mail clients.)
Lispers may also like to use LispURLs to "spread the word" (see "Trivia", below.) Of course, a knowledge of Lisp, or programming in general, is absolutely not required to use LispURL.com
If you add the LispURL.com bookmarklet [wiki] to your browser bookmarks, you can create a new LispURL for the currently visited page by just calling up the bookmark.
LispURL (<--bookmark this link)
The format of LispURLs is derived from a set of Lisp operators described here. The Common Lisp dialect described in that link defines "only" 30 of these operators, but in some implementations of some dialects of Lisp, each of our link names would be a valid, predefined function name.
