Diigo Toolbar - Annotate, Screenshot, Bookmark

In all honesty I never used any thing of this nature until being introduced to this tool via TT1221. This is a social bookmarking site used to tag and bookmark various web pages. This is a free tool that can be downloaded onto your tool bar, making the bookmarking process very easy.
