There is just too much cool stuff on the Internet! I have just discovered TED, a conference (and more!) that began as a change to gather people from "Technology, Entertainment, and Design" to share ideas. I think there best idea may be to limit presentations to 18 minutes. Seriously - can you imagine how much better most of the lectures you have attended lately would be if so edited?
Here is an example of TED that is buzzing around the 'net today and is about a technology/design program for kids. Gever Tulley of the Tinkering School talks about "5 dangerous things you should let your kids do."
