From Alex Bosworth’s blog via digg:

Ajax is an awesome technology that is driving a new generation of web apps, from maps.google.com to colr.org to backpackit.com. But Ajax is also a dangerous technology for web developers, its power introduces a huge amount of UI problems as well as server side state problems and server load problems.

Will you continue using Ajax? If you ask me, *I will * Some of the points that Alex mention are probably correct, but some are not. For example:

1. Not giving immediate visual cues for clicking widgets.

and

4. Blinking and changing parts of the page unexpectedly

This can be easily done using CSS. Simply prepare a message box using DIV attribute and hide it (display:none). Whenever Ajax is in progress, make it visible (display:block). This way, visitor know if there’s a progress going on, not unexpectedly anymore. My Ajax Tutorial also cover this technique.

For me, Ajax is wonderful. It’s not 100% secure right now, but again, it’s a wonderful programming technique. I’ll stick and continue using Ajax for now )
