Learnist, which I've described in the past as Pinterest for learning, announced today that you no longer have to use Facebook or Twitter to register and use their service. You can now register for and use Learnist with an email account. The service is still available only to people who request a beta invite, but it seems that beta invites come quickly.
Applications for Education
One of the obstacles to use of Learnist in schools was the requirement of logging-in using Facebook or Twitter account. The new option to register with an email address should make Learnist available to many more teachers and students. Learnist provides another professional
learning community in which you collaborate on the collation of resources that
are beneficial to you and your students.
