I put together a 'landing page' for the intelligence explosion concept similar to Nick Bostrom's landing pages for anthropics, the simulation argument, and existential risk. The new website is IntelligenceExplosion.com. You can see I borrowed the CSS from Bostrom's anthropics page and then simplified it.
Just as with the Singularity FAQ, I'll be keeping this website up to date, so please send me corrections or bibliography additions at luke [at] singinst [dot] org.
What is the difference between the ideas of recursive self-improvement and intelligence explosion?
They sometimes get used interchangeably, but I'm not sure they actually refer to the same thing. It wouldn't hurt if you could clarify this somewhere, I guess.
