I’ve started using Shaarli to organise my bookmarks. It’s a small php webapp to store website bookmarks that doesn’t require a database to function. It supports public and private links, tagging, storing notes, tag clouds and more. It also has a bookmarklet button to quickly add new links.
My shaarli is at http://remote.paulcolfer.ie/shaarli where you can see all my public links. You can download shaarli for yourself at http://sebsauvage.net/wiki/doku.php?id=php:shaarli
