Diigo, a company that specialize in social bookmarking service is releasing a new and updated of its core product, i.e. Diigo version 3.0. Diigo v3.0 comes with a completely new User Interface and code base, as well as over 100 new features has aimed to give its users a different experience in using the social bookmarking and annotation service. Based on the features of Diigo v3.0, it is undoubtedly that it has been cited as the top 10 research tools by CNET.

For readers that aren’t heard of Diigo, it is a free social bookmarking service that helped an user to highlight text or comment on a Web page, particularly if she just want to highlight one sentence from a 5,000-word article she found on the Web. There are in fact many free social bookmarking services available on the Web, such as del.icio.us, QQ Shuqian (China), Mister Wong, Xerpi, CoReap, and etc.

Apparently, masses of users access to these social bookmarking services and use it in hopes of achieving their own ends, it is unlikely for an existing player to offer the features that will suit all the users’ needs. Thus, I’m not sure this make Diigo to offer a bunch of features in order to cover all the needs of the users. However, as stated on Diigo’s press release, some of the features found in Diigo v3.0 are really impressive. Their newly features include the improved usability as a research tool, improvements as a team research platform, social browsing, personalized social content, and social information networking.
