I've created a new "landing page" on Friendly AI at Friendly-AI.com. This is similar to IntelligenceExplosion.com, Existential-Risk.org, Anthropic-Principle.com, and simulation-argument.com.
The site is less ambitious than the original plan for it was, but it serves its purpose.

On the topic of how the site looks in different browsers, and finding out whether the layout is borked on some browsers, you could use http://browsershots.org/.
At the moment though, it fails due to an internal server error when it tries to fetch http://friendly-ai.com/robots.txt. If you fix that, you should be able to easily see how the site looks in a bunch of different browsers on different operating systems.
