Media and causes
Ethan Zuckerman has a couple of recent posts about Darfur and Tibet, I found both very good to read. "China, bias, and misunderstanding" is about the disconnect between Chinese and Western perceptions of Tibet -- for example, how and why many Chinese were upset and offended by the Olympic torch protests. "Media, reality, representation: what are we paying attention to when we pay attention to Darfur?" explores the oversimplification made of the Darfur conflict -- it's much more complex than I've been led to believe! -- and he hypothesizes why this particular conflict has become such a popular cause for activism.
Gallons per mile
Bunnie's latest blog post is interesting -- I was fooled as he was. It teaches me that small improvements on the worst mileage cars is more effective than improving the mileage on cars that are already moderately efficient. I recommend it to anyone interested in the general issue of reducing gas consumption.
