Hello again; a short update:

Yesterday we dropped the beta subdomain. All our base are belong to you on a proper “www.lijst.com“.
Of course beta.lijst.com still works. Please update your bookmarks and API software so we can really drop it.

Since December 2008, you could use our basic API to access your Lijst.com data from software. This was implemented by Jeroen while I was relaxing in Montpellier, France. Today we added more unit tests, slightly changed the API specification.
If you like mashups, why not try it out? If you like, you can join my personal effort of programming client-side implementations for the API: code.google.com/p/lijstcom/
