There’s some Ajax stuff going on in the Guestbook now. Also replaced the old ‘Forum’ with a commenting function, in line with all the blogging websites. That also uses Ajax.
Used some sort of a Javascript library called Prototype which greatly simplifies the process. According to its website, “Prototype is a JavaScript Framework that aims to ease development of dynamic web applications”. But the documentation is a bit lacking. I found Sergio Pereira’s website very helpful in this regard.
For some Ajax lessons this seems to be a good place.

Another new feature is the Tag Cloud in the sidebar(“Things I write about…”). That was done with a little help from Jenny on Prism-Perfect.net.
