Does Anyone Use Delicious?

I'm not talking about food;-)  I mean the Yahoo site where you get to share your bookmarks.  I signed up, but I'm not really sure of the best way to create networks among those I want to see my bookmarks.  I don't only want to share with my friends, but I don't really need people in California calling about my next puppy class.

If you have experience on Delicious, would you mind sharing what you have done, and what it has done for you or your business?
