AJAX and Web 2.0 seem to be poping over all the web nowdays.

AJAX looks like old technology to me: javascripts scripts that are organised in librairies, like ruby on rails.

I'm not sure yet what web 2.0 might be. I'm awaiting eaerly b2b 2.0 :-)

I do not always agree with Daniel Glazman, but he got it right: Bullshit !
