I got evil-incarnate installed successfully, can’t believe you still need to edit a text file and upload it before you start the install. I thought this would have been addressed by now, as with most bloatware.
The AJAX side of things is merely a theme called Bloxpress, I have seen some other adaptations that are a little more advanced. But these seem to require too much mucking about to get installed and working properly, I’m sure we’ll start to see entirely AJAX based CMS’s real soon. The best mix of old and new that I have found is the unofficial V2 of the popular “Kubrick” theme. I’m currently working on a Web 2.0 themed template for this site, really just to poke fun at all the cliches of the style (gradients anyone ?).
