I have been thinking lately about the relationship between science blog style websites such as this and the popular science press VS journals. Where on the spectrum between a purely popular science publication... like "Pop Sci" and a journal like say the journal of the American Medical Association does science 2.0.
There is no peer review, but at the same time it isn't totally open either.
What is the place of websites like science 2.0 in relationship to the popular science media and journals?
