    No, there's nothing new about it at all. The technology has been around for years, it jsut never had a buzzword to go with it.

    Basically, in a nutshell, it's using javascript to send/receive information to and from the server and display it to the user without reloading the webpage.

    Ah - so is it like the old DHTML? (I haven't had time to look at it fully)

    not really dhtml, but that can be an aspect of it. AJAX stands for Asynchronus JavaScript and XML. it can do numerous things, but it's primarily situated around doing XML/Http requests, which basically means that one can do server calls client side without sending the page back to the server.

    and actually, if you notice the quick reply and edit features of this forum are using it (or it at least behaves like it)...

    OK thanks for enlightening me

    So (thinking out loud) in theory you could have the content of a whole site on one page... how would/does that effect SEO?

    I suppose if you use ajax for non content items - such as login boxes (like Google I believe) then you should be OK.

    I'm going to look into this more when I get time.

    depending on what you're doing, most likely it's not good for SEO as it's all JS driven.

    AJAX is pretty nifty.

    My only usage so far is for filling in txt fields after a user has typed some data. I believe the new VB uses this when searcing by someones username.

    the main thing that i've used if for is form validation, enabling/disable fields as the users goes along and not enabling the submit button until certain fields validate.

    Ajax is nice for form validation, agreed.

    Probably the nicest use of ajax I've seen in a while is in Mephisto's admin section. It's used for marking things saved, deleted, etc. It's quite nice. There's a link to the demo, and admin section for said demo on their site if you want to check it out.

    I use ajax on my site for the photo/image galleries.
