Tagging/Bookmarking

I find this would be helpful to someone who does a lot of bookmarking. It can be helpful but not to sure about it because of the privacy issue. You have to be careful what you bookmark. I am not too sure if I am comfortable with this because of privacy. However it would be a good way to access web sites that have been bookmarked from different computers instead of trying to remember where you saw something. I have worked with tagging before regarding photos. It is easy for a quick search.
