Educlipper is something I plan to sign up for this summer and start using. It has some similarity to Pinterest, but is likely able to be accessed in most schools unlike Pinterest. I like some of the options you could do such as making a clipboard of links and information for students and then sharing it with them. Or making clipboards of lessons and information and sharing it with your team or your content team. Or maybe you simply use it to keep track of your own units and concepts. Any way you use it, it could be pretty valuable. Good luck!
