Combining Ajax and WebDNA has some really cool possibilities. I've been trying to learn it in my spare time. You can reverse engineer what they are doing there... then you'd build the WebDNA that finds/retrieves the content you want. http://www.swoopo.com/prototype.js initializes the object.. http://www.swoopo.com/basic.js?t=8 (amongst other) does some of the details. I posted this a while ago: http://forum.webdna.us/eucabb.html?page=detail&threadid=287&category=252&start=1#287 which is code that initializes the xmlHttpRequest Object. However, if you are just starting out, there really is no short cut to knowing what you are doing other than taking a class or reading some books.
