Diigo

Diigo is a social bookmarking platform, very interesting because it allows you to organize, store, find and share the most interesting content on the web. Is a simple tool to use and that allows you to save all the sites, articles and videos we have read and want to keep on your own personal space, allowing us to create a library with the best content found on the web. The web is by definition the absence of order, a place - not a place of chaos, where access to information is free: Diigo bookmarking allows us not only to produce new knowledge, but to reorganize it and find it again if necessary.
