If you've talked to Jeff De Cagna recently, you've heard of the idea of moving from creating content to curating content. There's already plenty of information - people need help figuring out what to pay attention to.
Scoop.it provides a new option. And unlike other information curating platforms, it works with the inherent nature of the web, allowing you to curate a variety of formats (text, audio, image, video) in a visual way.
I haven't started using this, but Maddie Grant has, to good effect.
