Slightly off-topic: I'm completely amazed by the whole blog. It's structured well, fast, and they pay attention to details. In the figure caption of the charts/maps the author and sources are mentioned. The data is directly embedded and downloadable via octed-stream. The figure annotations in the margins are nice. There are different sizes of figures: some with the width of the text content, some with full screen width. There are different blog post categories which are listed in the blog header. All blog authors are listed on a page. In each blog post the author briefly introduces himself/herself.
