Directories are compilations of pointers to web sites created by humans, who typically write descriptions of entire web sites distilled into pithy one or two sentence descriptions.Īs the web exploded in size, labor-intensive directories fell out of favor in relation to algorithmic search engines which could easily scale to catalog many billions of individual pages. In the early days of the web, directories were the most popular information finding tools. Among the more popular are, Shadows, Yahoo’s MyWeb, Furl and newly launched Diigo. There are literally hundreds of these types of shared favorites services. The idea here is that if people save a particular page as a bookmark or favorite, they’re effectively voting for the page-fundamentally the same idea behind Google’s PageRank, but counting the “votes” of web users rather than webmasters. One of the first types of social search services to emerge sought to leverage the power of shared bookmarks. And since even people with a lot in common can also have widely divergent interests, they often contain “noisy” results that may not be relevant.

While all of these services can surface interesting content, they tend to reflect the biases and interests of their most avid users.
