I love Popehat, and Ken in particular, but any issue that intersects with his politics tends to get the same semilogical hyperbolic treatment. The "Buckyball" magnet thing was, if anything, even worse.
I rather liked the Buckyball article personally, but I wanted to note that Ken, while probably the best author on Popehat, isn't the only one and the Buckyball article wasn't him; it was Clark. Clark's articles are often the explicitly libertarian ones.
