Steve Schachter created the Memepool blog in 1998 which later became the foundation for his bookmarking website del.icio.us launched in 2003. He left his day job to work on del.icio.us full-time in 2005. By the end of 2005, del.icio.us was acquired by Yahoo. The document discusses how del.icio.us introduced the concept of social bookmarking and details the author's experience using del.icio.us until Yahoo announced plans to shut it down. It also explains how easily the author was able to transition bookmarks to the alternative service Diigo due to del.icio.us having open APIs and data formats.
