I think one of the things I enjoy most about blogging is how it focuses your attention on various topics within the sea of information out there on the Internet. For example, after my fumbling attempts to connect some thoughts on an environmental health research article with the need for clean coal technologies, I find myself reading a truly excellent Nature News article by Jeff Tollefson on just that topic. It’s a great introduction to a complicated field, and is helping a lot to deepen my understanding.
