Pindex is a new site that like many before it is attempting to position itself as “Pinterest for education.” On Pindex (still in private beta) users will be able to pin and share educational videos and infographics. Where Pindex seems to be attempting to separate itself from similar platforms is in offering digital badges for watching videos and completing short quizzes on a particular board.
Pindex is currently available only through an invitation. You can request an invitation on the site. I received an invitation a few hours after making my request.
