I just went looking to install RadioExpress again (moved computers a while back and had never installed it) and it had disappeared. It has a new home.

Doc Searls: Why I hate computing.

Doc's experience is why it is (in my experience) vital to enable Use Three Buttons in Radio. You don't want to necessarily publish what you've got, but you want to save it. When you've got Three Buttons enabled, you'll probably want to add a couple of scripts for easier management of your work-in-progress.

Interesting that this comes up when I answered a specific question about this earlier this morning. That kind of thing seems to happen a lot.
