Diigo is a website which allows users to bookmark and tag websites. It also
allows users to highlight all or part of a page and attach sticky notes to the
page. These annotations can be kept private, shared with a group within Diigo or
a special link forwarded to someone else. The name "Diigo" is an abbreviation
for "Digest of Internet Information, Groups and Other stuff".[1]
