A very smart friend suggests that people seeking information on the Internet don’t necessarily want the right answer, but rather an easily accessible answer. I was reminded of his comments by this from Matthew Nisbet:
In the digital age, information is found based on availability rather than accuracy. If different interest groups start blogs that attack peer-reviewed science, and the scientific community does not engage in similar communication mode, they will miss an important opportunity to educate the public.
This, it seems to me, is a strong argument in favor of RealClimate.
