Diigo, Social Annotation Tool
Filed in: Web — August 31st, 2006
Diggo is a web tool that allows to you bookmark, add note to any web page. It is more than social bookmarking, they call it “Social Annotation”.
Basically, Diigo is a combination of following features:
- Annotation — add a note to any web page.
- Clipping — highlight and save content of any web page.
- Bookmarking — bookmark the web page to several social bookmarking sites at once.
- Blogging — blog any web page using diigo web based blog editor
My two cents
Personally, I think Diigo is a great tool for online research. It would be a god given if I am a college student who always need to do research projects.
