Sharing bookmarks lets us mark web pages and share our thoughts on them. Sort of a way to organize the web. Also, for me,, sometimes I say "now what was that website" and the ability to search my own bookmarks becomes more useful the longer I use it.

Diigo lets us have a set of tagging standards and if you'll install the diigo toolbar, it will help us organize things!

So, what are the uses of social bookmarking, in your opinion?
