Educlipper and Evernote
As you may already know, this isn't a key differentiator. Tools like EverNote allow you to clip content and share it through various social media settings via RSS feeds generated per notebook. I point this out in my follow-up comment and link to my how-to on how to share from EverNote.
EduClipper lets you build clipboards into which you can post links, images, videos and documents and upload files to share with others. These clipboards can be private or public – that’s a key dfferentiator between eduClipper and its competitors– clipped for one’s self and/or shared to Twitter, Facebook, Tumblr, Pinterest, Evernote, and Edmodo or via email.
Of course, a part of me is wondering...maybe she meant something else?
