Social bookmarking, or using tags to organize web pages into a publicly viewable archive online, is becoming increasingly common among nonprofit organizations and supporting technologists. Social bookmarking tools are preferable to browser bookmarks or favorites in a number of ways, including accessibility from any computer, superior detail in archiving and retrieval and the ability to share our bookmarks as a whole or by tag with other people.

Most of the time it seems to me that the conversation about social bookmarking starts with del.icio.us - probably the most popular social bookmarking tool online. There are many more options available, however, and I thought it would be useful to provide some brief explanation of a few alternatives and some things to consider in making your selection.
