Buying YouTube is soooo material, get a higher ambition like Yahoo! and launch the Time Capsule project. In their own words:
Do you Yahoo!? This is where you can share a piece of your world with the global online community, and be part of history in the making. This time capsule is the first-ever collection of electronic anthropology, capturing the worlds voices, images, and stories. This digital mosaic of humanity will be projected onto an ancient pyramid and beamed into space before it is presented to Smithsonian Folkways Recordings, until 2020.
The ancient pyramid mentioned in this text will be The Pyramid of the Sun in Teotihuacan, Mexico. A mix of ancient art and new technology… Conceptual and interesting. Don’t miss the other experiments by Jonathan Harris.
