Same issue as you. So I don't care anymore.
I have 10/15 bookmarks in the top toolbar that are releant to my work. All the rest goes into limbo, and I don't even bookmark much anymore.
When needed, I write notes (wiki, or paper) with links contextualized by topic/need.
The problem with bookmarks is those 3 together (that are required for bookmarks to be of any usefulness - to me anyway):
1) it's easy to create one, there should be more friction;
2) it's hard to have a long-term storage/indexing system (Delicious & equivalents were a good direction);
3) it requires a custom setup for bookmark search to be integrated.
Also, in the mid-term, most URLs are broken.
A paper notebook, on the other hand:
1) requires a conscious effort to note something done (and to have around also);
2) is relatively a secure & long term storage; it's discoverable;
3) the effort marks a memory inprint that helps indexing in long term memory, just for the "I remember I noted that down somewhere when I was in...".
My offline bookmarks/notes/snippets/activities feel way more productive and fulfilling than the computer-based ones in the long-term.
