Murray Goldberg wrote to tell me about Brainify
"Brainify is an academic social bookmarking and community site for university and college students. You’ll notice that there are almost no members or bookmarks there yet – we will not be actively announcing it to students until the new year (it’s not a secret – students are just busy thinking about exams now). But I wanted to get the word out now to all my friends in the eLearning community to hopefully get a few people poking around it and giving me whatever feedback they may have."
Let Murray know what you think.
