Now there are thousands of blogs dedicated to science, yet only a few are popular. And strangely the popular ones are only loosely related to science. Just take a look at the top 5 science blogs (according to postgenomic):
1 Pharyngula (mostly about creationism)
2 Cognitive Daily (psychology research)
3 Living the Scientific Life (personal journal)
4 Sandwalk (some evolutionary genetics, and creationism)
5 Aetiology (pop science)
Of those only Cognitive daily is consistantly talking about peer-reviewed research. Why is that? Perhaps there is less appeal in discussing recent papers than bashing creationists. But bashing creationists is almost too easy, and not very constructive. It's been said before, you can't reason somebody out of a position in which they didn't reason themselves into. And it worries me because to the lay audience listening to PZ Myers (the 800lb gorilla), it would seem that science's purpose is to attack religion. In fact I suspect the blog gets most of its traffic from creationists. According to technorati, his top tags are "Creationism, godlessness, humor, kooks, politics, religion, weblog, weirdness", so should it really count as a science blog?
If you examine the elephant in the room, ScienceBlogs, the trend is maintained: politics, religion books, technology, education and music are tagged more often than biology or genetics. This suggests that their primary motives are entertainment rather than discussing science. Why? Because it pays. Seed Magazine and the bloggers themselves profit from the traffic. That's right, Seed actually pays these bloggers for their posts. And the whole ScienceBlogs thing is a little incestuous, they really like linking to each other, but not so much to the little blogs. I'm afraid gone is the amateur blogger, and in is the professional gonzo science journalist. Might as well read Seed magazine.
