The scenario – like me, you have multiple computers running multiple operating systems, and your bookmark collection is scattered across them. You’re looking for a better way to manage this. Check out foxcloud for one approach to this problem. It’s a firefox extension that can be configured to either store your bookmarks on the foxcloud servers, then synch to any browser that has the extension installed, or if you’re running your own server you can configure it to use ftp or DAV to store your bookmarks on your own server. This is a pretty slick solution and since you can run it on your own machine you can presumably get better performance than you’ll see with a shared server solution like del.icio.us (though now that they’re owned by yahoo this will probably improve) or storing them on the foxcloud server. It’s free and runs across all platforms firefox runs on. The only downside to it is it doesn’t support sftp.
