The toolbar is very powerful and has all the most commonly used features so you don't have to go through all the menus while logged into Diigo. You can have an rss feed of your bookmarks. There is a neat feature called "webslides" which makes screen captures of the site you bookmarked.

. | Overall recommendations | None | You can subscribe to other's pages, as well as save bookmarks for others | Yes, you can show or block R-rated or adult material | open people's pages/bookmarks in a new window | Overall, I think I would like using this site. It has many features that promote the social aspect of bookmarking and sharing. I have heard this site is generally used by educators, but since I could not find a way to filter out objectionable content, I am not sure if this would be the *most* appropriate site for student use. |
