Transmute Transfers and Backs Up Bookmarks Between Browsers [Featured Windows Download]
Windows only: Some browsers stash all your bookmarks and their metadata in a single folder that's easy to import to any other browser. For everything else, Transmute makes the work of shuttling bookmarks between Windows browsers much simpler. The simple but powerful application, also available as a no-install portable folder, supports nearly every major browser for Windows—Chrome, Chromium, Opera, Safari, and, of course, Internet Explorer and Firefox.

It's not quite as simple to get started with as something like Google Docs—for example, you'll need to be able to send other collaborators your IP address—but it's an incredible tool in its own right.
