Scoop.it lets you first identify a topic. Then, it continually finds items on the web related to that topic in a nice interface. Then, with one click, it lets you “scoop it” into your own personalized newspaper (that’s what I’m calling it, not them) which you can then share. It’s an ongoing process.
I really like it. Even though it’s not open to the public yet, I read about it in Mashable (that same post shares a list of other “curation” sites worth exploring — I think Scoop.it is the best on their list) and they have invitations available here.
I’m adding Scoop.it to The Best Sites For Creating Personalized “Newspapers” Online.
