For bookmarks, I love using del.icio.us. I can access my bookmarks from any computer, refer people to my bookmarks, and see what others are bookmarking. Delibar makes accessing delicious bookmarks even easier. You can click the Delibar icon in the menu bar to get a list of all your delicious categories. You can then drill down into ?subcategories? which are actually whatever additional tags you chose for the bookmark. I think Delibar is a slick way to work with delicious.
