Over the past few years, blogging ('web logging') has become a major social movement, and as such includes blogs by scientists about science. Blogs are highly idiosyncratic, personal and ephemeral means of public expression, and yet they contribute to the current practice and reputation of science as much as, if not more than, any popular scientific work or visual presentation. It is important, therefore, to understand this phenomenon.
