Amazon invest in Shelfari

Amazon has invested $1 m in Shelfari, a website where users input all of the books they own, and have an online visual representation of their library to share with others. Users can share their library through the Shelfari website or via a widget, and make money by linking to the books for sale at Amazon. It's a new idea of user generated content.

Let's see how it evolves.

Yahoo!!! Launches Pipes

Pipes is a RSS Mixer that gives the user a lot of freedom about what he/she can do. Let me give some examples:

• You want to look for specific news related with a concrete topic in a list of webpages (e.g., looking for Ferrari News in Road and Track, and Car Magazine)
• You want to find in NY Times all the references to crimes in a 2 mile radio respect to your apartment

It seems to be a very powerful tool but I think is too complicated for the average user, but you can copy pipes from other users to your own space.
