"Somewhere between Web and desktop search engines lies a new breed of 'community' search engines—sites where users share among themselves the bookmarks they've created and content they've encountered. Such sites can cut through the clutter that a typical Google search might return by adding the human element. After all, communities of knowledgeable, interested people can identify relevant sites with greater accuracy than a search engine. Plus, you can leverage the work already done by others and build on that base rather than repeat it."
