MIT's Technology Review
If you haven't visited MIT's Technology Review, spend some time there. The articles are always interesting. Visit the infotech section and check out the videos. Lots of interesting ideas such as machine listening, virtual reality and mapping, sociometrics, evolutionary design by computers. Jeff Han talks about inventing the multitouch screen. Bruce Sterling explains why many technology designs seem hostile. Tim Berners-Lee talks about the Semantic Web. The videos are short -- 1 to 8 minutes -- but contain much food for thought. I also recommend the special reports on 10 emerging technologies.
