Here's my new label cloud, which I'm pretty impressed with - hopefully, it'll be much easier to explore previous entries now. Clouds also make it possible for bloggers to use far more creative labels in a useful way.
The instructions on how to do it are a bit complicated, but worth wading through. You end up with a beautifully-organised list which shows you precisely what subjects/obsessions a blogger has to share with the world.
Or it could just be an enormous waste of time.
