Social bookmarking.

Social bookmarking is a internet tool that lets us organise, use and share information more efficiently. It works in a way that is similar to the Favourites option of a browser program. Some of the most popular social bookmarking applications are:

- Delicious: Is a service that lets us save our favourite web pages along with a description and a list of key words for easied classification.

- Diigo: Defines itself as a 'multi-tool for knowledge management'. Among other functions, it lets us bookmark the pages that we visit and create a digital library in the cloud, with links, notes and images.

- Evernote: We can add notes and share information with other people. The application also has a search function for finding specific details in the content that we have saved.
