I love reading Dave Weinberger's blog; his excitement at the ways technology can augment the world mirrors my own. I love this post for the reduction of where Web 2.0 and ubiquitous metadata are heading us: "When all our works are digitized, a local library will be nothing but a playlist."
Think about that ... mash up Google Books with a video iPod and BAM -- it's a library in your pocket. Toss in Audible.com and it's even better.
I'm with Dave ... I can't wait!
