It is about time that we change some of the browser paradigms. Bookmarks/Favorites don't work. We use deli.cio.us these days, and before even going to that we use Google.

Flock also gives you a blogging topbar, aiming to merge our browser needs with our blogging ones.

This looks great. Memestreams integration would be important, because I can imagine straying to one of the other services with that kind of simple interface.
