"Web 2.0" features enhanced interactivity which means that the web page possesses the rich, responsive interface we normally associate with desk-top applications. Web 2.0 has been propelled by a renaissance in the use of client-side JavaScript and the AJAX paradigm (Asynchronous JavaScript and XML). An ajaxian web page refreshes only specific content, not the whole page. JSON - JavaScript Simple Object Notation simplifies the XML pay load.

AJAX plus JSON would make the acronym AJAJSON, which is unpronounceable by most people, so AJAX continues to be used. :-)

Terry,
I decided to alter the second AJAX assignment slightly, and I noticed that when you 4 instead of 3 names, the children (well, the ones that are not IE) have to be 1, 3, 5, 7.
Why not a straightforward 1, 2, 3, 4, ? It's not like these names have parts to skip. And if it's a question of the XML tag ... they are all the same tag...

Terry talks...

Note that if you're using Firefox, it counts the text nodes. Hence node[0] is a text node, node[1] is a name node, node[2] is a text node, node[3] is a name node, etc.
