What is social bookmarking?
Delicious
Instead of having different bookmarks on every computer, Delicious makes it easy to have a single set of bookmarks kept in sync between all of your computers. Even if you're not on a computer you own, you can still get to your bookmarks on the Delicious website.
If your friends use Delicious, you can send them interesting bookmarks that they can check out the next time they log in. Of course, they can do the same for you. As you explore the site and find interesting users, you can use our Subscriptions and Network features to keep track of the Delicious tags and users you find most interesting.
See what's hot with Delicious users by checking out our popular tags. By looking at popular bookmarks for a tag, you'll be able to discover the most interesting bookmarks on the topics you're most interested in. Browse bookmarks on just about anything from the best programming tips to the most popular travel sites, all in an easy to read format.
Diigo
Diigo is another social bookmarking service (and one we’ve covered before), offering all of Delicious’ relevant features and much more. I left Delicious, and haven’t ever looked back. There are a lot of things I love about Diigo, but there are seven features that sold me on using Diigo for all my bookmarking needs.
Have you ever wondered how you can share your “diigoed” page with someone who may not be a diigo user? No problem ~ it’s actually quite easy with Diigo’s innovative “Get Annotated link”!
Diigo’s “Annotated Link” is a special URL provided by Diigo that allows you to share the current webpage complete with highlights & sticky notes to anyone. Here is how:
Diigo's WebSlides, http://slides.diigo.com, is an incredibly easy way to convert your bookmarks and feeds and present them as live web pages in an interactive slideshow format - complete with the full conten pages, links, comments, and ads. It enables a new way to easily create and share unique presentations based on web content and user annotations.
In addition to tags, and better than folders, "List" is a great way to organize, share and display specific collections of bookmarks. Once you add bookmarks to your list, you can easily drag and drop items to arrange the order in any sequence that you'd like to present. Best of all, once you create a list, when you click the button, you can browse, play and annotate any list of URLs as a slide show! It's great for content browsing, sharing, and creating unique presentations based on web content.
Diigo Groups provides a ground-breaking collaborative research and learning tool that allows any group of people to pool their findings through group bookmarks, highlights, sticky notes, and forum.
