Have you checked out Scoop.it?
If you like StumbleUpon but don’t have a lot of time keeping up with all the shares and information, you just might want to check out Scoop.it.
Scoop.it is a new curated site gathered by its users and even though there is no true voting happening, you are able to like the content that is shared. They have allowed you to create boards that you can name and tag to fill with relevant images, articles, videos or anything else you see fit.
Once you have created a Board you will then receive related news in a real-time fashion to either add to your category or you can dismiss it for another news article to replace it. Follow other people or boards and rescoop their content.
Scoop.it is a great site to find information on interests you enjoy.
