Commercial? Yes
Type of site Social Annotations, Highlighting and Social Bookmarking
Launched July 4, 2006
Current status Active

Diigo /ˈdɡ/[1] is a social bookmarking website which allows signed-up users to bookmark and tag web-pages. Additionally, it allows users to highlight any part of a webpage and attach sticky notes to specific highlights or to a whole 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 acronym from "Digest of Internet Information, Groups and Other stuff".[2]

Premium account holders can perform full-text searches of cached copies of bookmarks. A full-text search also searches page URLs, tags and annotations.[3] This means that premium account holders can choose to omit tags that already appear in the text of a page to be bookmarked (although text inside images cannot be searched).

The launch of Diigo met with mixed responses, from the unimpressed[4] to the enthusiastic.[5] Diigo beta was listed as one of the top ten research tools by CNET in 2006.

Outside the website, Diigo's graphical user interface includes an optional bookmarklet, or a customizable toolbar, with various search capabilities. Highlight is enabled by a menu, that can either appear automatically when content is selected, or be embedded into the context menu.

In March 2009, Diigo acquired web-clipping service Furl from Looksmart for an undisclosed price.[6][7]

The site also has an extension available on the Chrome Web Store.[8]

On October 25, 2012, the diigo.com domain was hijacked.[9][10] An unknown attacker changed the authoritative nameserver records ("NS records") for DNS zone DIIGO.COM, temporarily giving control to nameservers at AFRAID.ORG, and causing traffic to be misdirected.[11]

Mobile apps for Diigo are available on iOS, Android[12] and Windows Phone 7.
