Saving browser bookmarks... and Saving time...

Was wondering if anyone knows about a current application that can help do this (below) kind of thing.

I save my links and create them as bookmarks on my browser.
When I go to another computer, I need to do the same thing again.

It would be very useful if I could log into a different computer and access the links already created. This library of links could be useful when reformatting the computer, and even allow me to share my links with another, without arduous cut and paste...

By making some site holding the links a homepage, perhaps integrating with other applications like email, much time could be saved and much frustration avoided.
