Tagging and Social Bookmarking

Del.icio.us is an incredibly powerful site. I set up my own account and bookmarked mtlib20. Now instead of having to be on my own computer to view favorites sites I can log onto my account anywhere. Del.icio.us is as amazing as is endless. I could spend hours on this site. I found tutorials on software, music, recipes... the list goes on. This site can also be useful for research assistance. When I type in a subject I get not only the bookmarks but also tags. The subject area then has a continual link to other sources and quickly gets you to the place your looking for.
