del.icio.us
I’ve been playing around with del.icio.us recently. If you haven’t run across it yet, it is a fairly niffty bookmark manager which allows you to classify (or “tag”) your bookmarks, so that you can find them easily. It allows you to access your bookmarks from any computer connected to the internet and also to find bookmark collections of other users who have linked to the same site that you have bookmarked, which in turn can lead you to new interesting sites that they have found.
You only need your web browser to access del.icio.us, but there is a nice freeware Mac client available, which makes the experience even more convenient than it already is: Cocoal.icio.us (there doesn’t seem to be any Windows client available at the moment), and if you want to back up your bookmarks into your Safari bookmark collection, the program you need is Chistina Zeeh’s delicious2safari.

We’ve added a link to our del.icio.us bookmarks in the menu on the right, but we still have a large backlog to transfer and tag.
