How do you organize great bookmarks?

Having stumbled upon some great articles about marketing, software, funding and other interests I've realized that I have no great way of organizing these resources. The best I've got is a jumbled mess of bookmarks, with no notes, I rarely look through.

I ideally want a system that is great for personal resources in which I can add notes, personal thoughts and findings and that is easily shareable with teams.

How are you guys managing the resources you stumble upon? Have you found a super-bookmarking system, and if so which one (or which combination of apps)?
