Bookmarks
I'm trying out del.icio.us to make a subset of my bookmarks available via the web. I used to use Google Browser Sync with Firefox but the del.icio.us method means I can access my bookmarks from any PC, anywhere, without having to use a Firefox extension e.g. at work where I have to use IE6 behind a heavy firewall. It also means you can look at what I've been bookmarking, if you're interested..!
