Social Bookmarking is the process of sharing links or as Wikipedia says: On a Social Bookmarking system or network, users store lists of Internet resources that they find useful. These lists can be accessible to the public by users of a specific network or website. Other users with similar interests can view the links by topic, category, tags, or even randomly.

I have used Del.icio.us for at least a year and have found it very useful to share and get links for folks I follow in the blogosphere. On my way in to work, I listened to EdTechTalk.com’s podcast on Social Bookmarking and was turned on to a couple new players in this arena. Diigo is a new tool that allows much of what del.icio.us offered but with the ability to add more features like sticky notes, groups etc. I am going to give it a try. JKN.com is another one that allows you to add comments to pages. Trailfire is a tool that allows users to navigate a “trail” of links put together by a teacher with questions or comments along the way. I have not tried it but it sounds interesting. These tools make it simple for a teacher to make links that they think are important available to students. In fact it could become a class activity to find web sites on topics and “tag” them so they show up in the social sites.
