Just a short note on blog schedule. Historically, I aimed on this blog to do a post once each morning on weekday mornings. This was never perfectly true: I always missed the odd morning when something didn't work out, and have occasionally added extra lunchtime or weekend posts as time and interest allowed.
However, in recent months I've had a lot of work-related travel and I've been failing more consistently to do more than a few posts each week. I think it would be better to acknowledge this explicitly and provide readers with a bit more predictability by switching to a target schedule of posting Monday, Wednesday, and Friday mornings. Again, this won't be perfectly true, but I'll aim to make it true 90% of the time. Posts will continue to be primarily quantitative/empirical exploration of issues in the area of energy/environment/economy with a focus on things that I think are important but not well-enough covered elsewhere.
