Snapzu is a new social media and curation tool. It feels like a combination of Pinterest and Scoop.it. Basically, you set up a profile, choose a bunch of "tribes" to follow, search and discover content, and create and share posts from your curation as well as new posts you create. It's now in beta stage and is worth exploring though the number of topics and members is still small.
Time will tell if there's room for another social media channel like Snapzu but its features and design are well done.
