Kasper just did a good introduction, complete with explanations, clean code etc.
You won’t find that here, just some of the things I’ve done recently, including hardcoded URLs, IDs etc. You’ll figure it out, I’m sure.
Thanks to Niels for the introduction (he made the del.icio.us one). This is incredibly easy — otherwise I wouldn’t have been able to do it ;-) But you might as well grab thesee now that I’ve made them.
