I wrote to Merlin asking this same question, and he wanted to see what everyone here thought (plus I thought it'd be a great way to start being active, as I love listening to the Mann as many times a week possible!)

I visit Digg and StumbleUpon a lot visiting many websites a day, and a lot of those I usually end up bookmarking for some sort of value, be it to show friends later, or it was a cool site that I thought would somehow be useful. I already use Foxmarks, as I'd probably cry if I were to lose allllll my bookmarks, but my question to you guys is what way do you sort your own bookmarks? I watched the Inbox Zero presentation from Google the other day and loved it and wondered how that might be applied to bookmarking sites, anyone attempted already?
