The growing market of social annotation sites will get bigger next week with the launch of Diigo.
Diigo, which is an abbreviation for 'Digest of Internet Information, Groups and Other stuff,' has been in a closed beta trial for most of this year. It will be released to the public on July 24.
The testing has been exhaustive according to Maggie Tsai, co-founder of Diigo.com, who said the company has had input from over 10,000 users from all over the world.
Diigo, (pronounced dee'go) allows users to add highlights and put up sticky notes (directly on any part of a Web page). These highlights/notes are then saved in a Diigo tab situated at the top of the browser. When users click on the tab a list of all saved articles along with their URLs appear. Clicking on the relevant links yields not only the article, but all the highlights and sticky notes.
Another new feature allows users, with a single click, to convert their Diigo highlights and sticky notes to their blogs, removing the need for copying and pasting.
Diigo also allows bookmarking to competing services such as de.licio.us, Simpy or Furl.
"Regardless of competition, we believe in providing the features that users really want. Our users really appreciate this unique feature because it is hard for them to make the switch overnight even if they recognised that Diigo is much better and powerful than these other services," Tsai said.
The service runs on Windows XP/2000 SP4+, Red Hat Linux 9.0+, Mac OS X 10.2+ and is available through a downloadable bookmark, or a browser button for IE 6.0+ or Firefox browsers.
