I can't believe no one has mentioned XMarks.com I've used them for years. Can't imagine using anything else.
I keep a minimal amount of bookmarks, only ones I visit daily.
For archiving, I use Kippt.

It also has a nifty backup service allowing you to restore previous versions of the bookmarks, should you have erased something important or something else. There are also other services (password sync and open tabs sync) which I don't use.
I use it to store ~2000 bookmarks in a loosely disorganized set of folders. My biggest grief is that Firefox's bookmark user interface is terrible (and Chrome's only slightly better), and it becomes painful to use when you want to classify hundred's of bookmarks.
