Wtf is a Pearltree?December 15, 2009
Great question, and one that I’m glad you asked!
A Pearltree appears to be a user generated idea network set over an infinite canvas. It features click and drag, but not zooming, to navigate the branching nodes of interest. As a user, you can create an interest network and connect areas of it to those created by others to grow your… tree. The following video explains how to use the site:
I must admit that even after tooling around on the site, and watching the video, I am still a little bit lost. The idea is really fascinating and I love the social aspect of it, but the implementation seems kind of wonky, even discounting the lack of zoom.
