Macintosh users with Apple's Dot Mac service now have the ability to synchronize their bookmarks between their Macs and also to use those same bookmarks from anywhere on the internet.

Once enabled, your synchronized bookmarks are available through the web interface at mac.com. I've tried it and it works reasonably well, even if you are using the bookmarks on a PC.

When accessing the bookmarks from the web, they pop up in an additional browser window that you can leave sitting to the side of the main browser screen (if you have enough screen real estate). Once the window is up, you can use the same groupings and a useful subset of the maintenance features as in Safari's bookmark window.
