This paper presents results from three studies on science blogging, the use of blogs for science communication. A survey addresses the views and motives of science bloggers, a first content analysis examines material published in science blogging platforms, while a second content analysis looks at reader responses to controversial issues covered in science blogs. Bloggers determine to a considerable degree which communicative function their blog can realize and how accessible it will be to non-experts Frequently readers are interested in adding their views to a post, a form of involvement which is in turn welcomed by the majority of bloggers.
