If you've been trying to email me in the last few hours, it will have bounced due to an overload at my host. It should be working again now, but you might need to resend. The same may have happened if you tried to visit this blog today. My apologies.

On another technical note, prompted by David Weinberger, I've added the neat little Technorati widget that lists blog reactions to each post. We'll see how well it works in practice. Better than my email I hope.
