Having a first-class UI for bookmarks really does make a difference. I used to agree with some of the sentiments expressed in comments here - that bookmarking is a write-only activity, that just feels satisfying without actually being useful. Then I started using Zotero for my bookmarks, organizing them into collections, tagging them, adding descriptions ("Abstract"), etc., and I find that I actually go back to them a lot more, and find it really useful.
The UI browsers provide for bookmarks is pretty atrocious, and seems to have been the main reason I didn't go back to use them much - which I didn't realize until I had the idea to use Zotero as a bookmark manager. It has a lot of the features that Grimoire lists, including separate "user accounts" - I have a separate Work profile, for which I've created a desktop shortcut the same I do for Firefox [1], with its own collections and tags.
