A while back, I wrote about bookmarks. Since then, I've found del.icio.us.
I don't love the name but the service is great. Basically you create a (free) account and post your bookmarks to their system. Not only is it available on any browser but also it's available from any computer connected to the Internet.
Moreover, you tag bookmarks so it's easy to search through them.
It's also Web 2.0'ish, so it encourages "social bookmarking", for example sharing bookmarks with others, seeing what others are bookmarking, or flagging a bookmark for someone else. You can share (or not) your bookmarks with anyone else.
Check it out, my bookmarks are here.
