Now THIS is refutation. Ampersand has gone to the time and effort of completely destroying another argument; not by the immature and ultimately pathetic process of namecalling and obfuscation that is "fisking", but the proper way... research, organization, refutation and with an objective and evenhanded approach to the subject. Hell, it includes a bibliography, which means there's no question about sources, either.
Is it blog material? I'm not sure; blogs are usually a quicker format, and are heavily influenced by the freeform rhetorical style of Usenet. Since blogs are web pages, however, it might be a good idea to remember that occasionally there needs to be more to a critical blog entry than linking to friendly sources and heavy extrapolation from barely relevant fields and experiences.
