In FAQ #6:
Friendly AI is a problem of cognitive science.
I think this un-argued-for assertion makes the site seem (and be) less rigorous. Unfortunately, I can't think of a better concise justification for why FAI researchers should read about cognitive science.
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.
