Ask a ScienceBlogger: Scientist, why do you blog?

A reader asked: “There are many, many academic bloggers out there feverishly blogging about their areas of interest. Still, there are many, many more academics who don’t. So, why do you blog and how does blogging help with your research?”
Good question, simple answer: “Much like other bloggers of any orientation, background and intention I have deep seated need for attention.”
There are some other reasons, of course.
