Diigo is a social bookmarking website similar to Delicious. I have been evaluating Diigo as a Library Subject Guide based on the Swiss Army Librarian’s blog post Library Subject Guides Using Diigo.
Users can import their Delicious bookmarks into Diigo and create a linkroll to display their bookmarks on their website or blog. I am using this blog post as a way to experiment with Diigo’s linkrolls to create a Health Subject Guide.
