I mark link according to their distance. The following may or may not look different on your browser: Absolute (remote) links: before visiting, visited Relative (site-local) links: before visiting, visited Internal (page-local) links: before visiting, visited Mnemonic: red like remote (and slow), fast is green (same page). Blue is not fast, but neither conceptually remote. This is an excellent idea, marking the links depending on where they lead. Yet another reminder of how flexible most things can be, if used a bit outside the box. And – encoding information in the color of the links is something I /could/ use!
