Pearltrees Social Curation Tool
I'm using Pearltrees to curate, organize and share web resources. It's one of the most convenient and productive social bookmarking tools available. You can double-click on pearls to expand branches and reposition trees in the window by dragging the background with the mouse cursor. I add interesting and useful resources on the fly via the Chrome Extension.
Two of my social curation channels for music and images. Click through to visit the sites.
