Bookmark Synchronizer Xmarks Hangs up their Hats

It would still be nice to have a single way to keep my bookmarks from my work machine in sync with my home machines and my mobile devices without exerting much effort. Xmarks seemed to be the only ones with that clear vision, maybe the replacement tools can grow into this space, but it's still a little sad to see a useful tool wave goodbye.
