Social bookmarking

Social bookmarking is an online service genre that allows users to save and categorize (see folksonomy) a personal collection of bookmarks. Distinct in that others may see the bookmarks that have been saved by others and add them to their own collection, as well as to subscribe to the lists of others.

Drawbacks of current implementations include: single word categories (n.b. Simpy supports multi-word tags) , no mechanism to define or refine categories, no synonym/antonym control or related terms & no hierarchy.

A useful feature is RSS feeds per category (tag) that you can subscribe to - alerting you to new links in your areas of interest.
