I've been using http://historio.us for a few weeks now and have been impressed. Now, I've not looked at other services, but I think its great that I don't have a desktop filled with shortcuts that I will never use. Indeed, it's really helped me a few times when I know what was on a site, but not what the site was called - a quick search and I find it. It makes life easier and the free version will handle up to around 300 bookmarks I think. I did pay for the full version and was a bit disappointed that the 'tagging' was handled after the bookmarking (so I never use it) but its a good service.
