	Web 2.0, AJAX & SOA Power Panel with Jeremy Geelan

	Hi Dion, You are correct if your definition of a web service doesn't require interop through wsdl. With the idea of web based services and the web 2.0 movement, you were completely in context. Being a developer, it takes on a different meaning to me and none the less, a great show!

	Congrats... sys-con has learned how to do in-page pop-ups with DHTML. Pop-up blockers are defeated, and web sites are once again completely annoying. I suppose I could just turn off Javascript, but it seems better to me to just unsubscribe from the email newsletters and stop visiting the web site(s) altogether. Sys-con learned the technical lesson, now they should learn about the user experience (again).

Don, thanks for watching the Web 2.0/Ajax/SOA show.

I appreciate your comments but the statements I made are indeed correct. I think our difference probably comes from what we think a web service is. I'm from the growing school of thought that says anything served up via HTTP is a valid web service. This includes not only RSS but REST, SOAP, WS-*, etc. There are non-HTTP bindings for these of course but that's not what the vast majority of most people use, nor will they in the future.

And Ajax does indeed require web services. Once an Ajax app is loaded it must XML/JSON/* packets over HTTP in order to read and write information asynchronously back to the Web server without reloading the page. It does this through JavaScript's XmlHttpRequest() method. So, if you are just using DHTML to manipulate the web page and you're not calling Web services, then you're technically just doing DHTML, not Ajax.

I hope that helps!

Thanks,

Dion

	Dion is not accurate in his comments regarding AJAX and RSS. There is nothing that states that either of these tecnolgoies are or have to be based on web services.
