Shadows is a social bookmarking service for discovering, sharing and managing information on the web. Shadows supercharges this information with a "Shadow Page" — a community blog for any web page that includes views, ratings, tags, and comments by you, your friends and the Shadows community. Rediscover parts of the web you may have visited but couldn’t remember. Discover new people with interests and opinions like yours, and places you wouldn’t find with standard search tools. Build the Shadows community as you tag, rate and discuss your favorite websites, and enjoy the information shared by you, your friends and others.
