my php-driven thoughts

Have read a few articles on Ajax. The newest fashion-tech-rage at the moment. Have some thoughts on realizing it in my job (got quite big project at the time with death-line marching in). First thing on my mind - as any other good thing it has own drawbacks. Quite some coding must be done to make a page with ajax /(fool|hack|xss)-proof/. At current situation most of projects are based on "must-code-quickly" and not "must-code-to-make-good-performance" aspect 'cause of current hardware on the market. And for this we have abstractions, wrappers and other thing to make us live (and code) with b[u|i]gg[i|]er performance.

If anyone is reading this, could you please provide me with some actual applications? I mean lots of frameworks (namely PHP, dunno about other languages) are Ajax-based, but web-site? A colegue gave me some links (oh, and please don't forget almighty GMail (tm)), but i haven't been convinced about using it in small projects which require little or none server-side coding.

Just makes me think of upcoming new technologies (yes, i know, that ajax is not a technology), what next? Make a webpage, that can shake you Shakeratto (i think i mis-spelled it)? And again everyone will be reading megabytes of api-documentation, tutorials, articles'n'stuff. In a few months everything will be forgotten. Until other tech-fashion-rage comes.
