Diigo - An Ultra-Cool Social Bookmarking Tool

Diigo is an online bookmarking and annotation tool. Users can save webpages they have marked on the Diigo website and can also view annotations made by others on those webpages. Additionally, users can create relevant groups to discuss topics of interest with others. Online bookmarking services function as a personal information management platform. Leveraging its unique advantages on the internet, it provides many functions that local bookmarking tools cannot offer. Its core value has evolved from simply saving viewed webpages into a new center for information sharing, truly achieving "collecting within sharing, and sharing within collecting."
