"David: You correctly complain that Steve McIntyre's blog articles are not peer-reviewed science. They are, however, "peer reviewed" by literally hundreds of climate scientists and highly educated readers who would love to catch Steve McIntyre making a serious mistake."McIntyre's readership is a self-selected group. Such groups are known to exhibit significant biases, which is why polls taken from them, such as the Internet polls some newspapers now run, are meaningless.
If that population was the group participating in a clinical trial, its results would be laughed out of any journal in existence. For good reason -- it is not representative, and McIntyre's readership certainly does not constitute anything like anonymous peer review from experts.
Blog posts are not science. In certain hands, though, they are harassement, which is mostly what their blogs are about.
