Facebook etc

This article pretty much sums up how I feel about "social networking" sites:

File Sharing

I was not aware of the existance of share programs such as google docs until now. It will be very useful at our library - often customers come in to the library and work on a document (a letter for example) but don't bring a saving device. They can save it to the hard drive, but at the close of business everything is wiped. I will certainly recommend google docs to such customers.
I also like the collaborative potential of these programs.
