In 2003 Joshua Schachter changed the way that people organize
information online. He released http://del.icio.us (the most annoying
popular URL in history) and introduced the world to social bookmarking.
(The URL has since changed to http://delicious.com.)
Delicious is a repository for articles that users want to “save.” Because a
web browser’s “favorites” or “bookmarks” feature is only as effective as auser’s ability to always use the same computer and browser, Delicious is away to have access to all your saved articles, blog posts, and reference material wherever you are, as long as you have an Internet connection.
When you “tag” an article at Delicious, it’s as if you’ve saved it in a file
folder with that tag name In other words, an article about how to perform a 301 redirect on an ASPX site might be saved under the tags “301,”“redirect,” “IIS,” “ASPX,” “SEO,” and other tags such as the author’s name, name of the site
or blog, and so on.
