I've pretty much stopped using any bookmarking service. If something is important enough for me to remember, I file it away into one of several files (my custom categorization system).

For example, if I come across an interesting JavaScript library, I add it to javaScript libraries along with a sentence or two that gives it good context for why I should be interested, what problem it solves, etc.. Someone recommends me a movie? I access all these files quickly through nvAlt that syncs to DropBox so I can acess from all my devices.

I found that no matter what service I was using, delicious, springpad, etc., I was only hoarding links and never really using those tools to look them back up. I was essentially "saving" them to satisfy some hoarding need or something. Often, it is just faster to do a Google search to something I remember saving, too.
