As promised here is my review on PearlTrees:
Always on the lookout for unusual and unique applications Peartrees caught my eye. Instead of the mundane boring web bookmarks Pearltrees saves them as little circles affectionately called pearls. Instead of the usual shortcuts that most apps have to take you directly to a website you have pearls. The pearls are movable and you can forms "trees" in different categories.
I have my Blogging websites in one "tree "which branches off to Wordpress and Blogger "pearls".
