Social Bookmarking

Just finished Social Bookmarking/Delicious - the amount of information available here was overwhelming. I would definitely use this at home - not at work. I can see how this tool would be invaluable to a person doing research. I will keep this site in mind the next time I feel I need to "research" something. Not sure I would be able navigate through all the options that are available on this site. I would need much more practice.
