Javascript-Only Sites?

My advice, if you want to use JavaScript then use it. Sure it would be nice if your site degraded properly, but that takes a lot of work and might not be feasible. Just make sure you include some noscript tags to alert users that your page requires JavaScript.

If you want to go full Flash, then do it. To say a Flash site is "stupid", is itself "stupid". On levels of visual appeal and interactivity, Flash can be far more expressive than HTML and DHTML. The Flash player is installed on 99+% of all machines, which means it is probably the most ubiquitous piece of software that exists right now. Just do it properly and alert the user should they not have the plugin installed. Chances are that if your site will benefit from Flash, a user who doesn't have the plugin installed wasn't in you target demo anyway.

Sure there are drawbacks to heavy use of JavaScript and Flash, but there are drawbacks to heavy use of all technologies. The standards compliant crowd needs to relax.
