Speaking of nanotechnology, Ray Kurzweil has a fascinating site on emerging technology and futurist trends, with an emphasis on nanotech developments. This site is also one of the first to use a really cool information neural net from TheBrain Technologies on their website. It makes for an interesting way to navigate a site and its many links. I’ve been using Personal Brain off and on for about a year now, and WebBrain is the internet enabled version of that technology. TheBrain at KurzweilAI.net is a treasure trove of links to a vast array of subjects archived on the site. Truly a first rate implementation of a promising technology on a gold mine of a site.
