Comments from some of those who selected Diigo as one of their Top Tools

“Although the functionality of an online bookmarking tool overlaps with Evernote, I find Diigo to be more convenient for saving bookmarks. So much of the appeal of a tool is the simplicity of its user interface and functionality. Diigo does well in both these categories, in my opinion. The tagging and search features are straightforward. And you can add a Diigo toolbar to your browser. This is an excellent way to bookmark articles for future research or reading.” Connie Malamed, 2014
