Chad Orzel is a scientist who blogs, and he sounds uneasy about increasing competition from professional science writers: "I worry that the professionalization of the hobby is squeezing out the, well, hobbyists. One of the things I try to stress is that blogging is a low-maintenance activity — it can be done on a strictly hobby-type basis, by people who do not have and do not necessarily want careers in science writing. Blogging doesn’t have to be a career."
