I Digg...

This social bookmarking tool, and others like it, really help to spread information on the Web quickly. This tool is useful for me because it allows me to access bookmarks on any browser and on any computer.  It also helps me connect with my friends and check out the sites that they enjoy.  The integration of Facebook, Google, and Twitter really give Digg a powerful database to work with. If you have a Yahoo account, I recommend Delicious as your social bookmarking app.  But, the ability to integrate my Google and Facebook contacts directly into my Digg account gives Digg the preference in my book.
