I recently discovered Treebu, a very useful chrome extension for productivity and note taking, which allows the user to select text, images and videos extracts (Youtube) simply by dragging and dropping.
The extension also provides an ultra powerful search engine (a kind of augmented google) that adapts to all search engines and websites.
Have you ever tried it and is there any chance that one day it will reach a critical threshold of users to be truly relevant ?
