"Facebook Prototypes let us share the experimentation going on inside the walls of Facebook with the rest of the world. You'll be able to test any of the products and features we launch as Facebook Prototypes and then provide feedback directly to those of us who built them. To access Prototypes, visit the Application Directory and filter by "Prototypes." From there, you can activate or download any of the Prototypes listed." Neat little one off Facebook experiments.
"Google has unveiled a service called Fast Flip to let users consume news more quickly and to boost the flagging fortunes of the news industry." It's pretty neat.
