Got a half hour? Why not spend it listening to a TED Talk. It seems that the Internet should, at the very least, be storehouse of innovative ideas. TED is a great starting point.

Wondering where to start on the site? I suggest the theme of how we learn. You can listen to Nicholas Negroponte, Dave Eggers and many others.

Some kind soul has created a frequently updated Google spreadsheet to sort the talks by topic and speaker. It is a handy way to find a topic of interest.
