Its wonderful improvement to web...
What are your opinions?

Bleh, one way or the other. Guess it speeds things up but it's nothing big.

I always think of the cleaning substance when people mention it though.

Hey ive messed around with Ajax. Make sure if you want to use XML with it from php set the header

header('content-type: text/xml'); 

Spent ages trying to fix the javascript when it was really a PHP problem.

Check out this, its what got me started.

basically, how this workS?

Essentially all it is is making HTTP requests from Javascript using the XMLHttpRequest object, so that you can update client-side content without a full refresh of the page.

ha, I just found out about AJAX two days ago on PHPClasses.org and seems to hear about it all the time ever since!

I think it's amazing for friendly userness... is it slow or anything? Does it have any cons

I heard that it is a resource hog. Not sure how true that is though.
