Why the name "woo"? The fact that this is likely to occur in the same context as "woo" as in "woo-woo" makes me uneasy; it seems likely someone not paying attention might actually get them confused. (Well, one is a count noun and one is a mass noun, but...)

Yeah, that's the first thing I thought of too. Especially since I often hear "woo-woo" itself abbreviated to just "woo". I think it should be renamed, especially since a lot of people interested in the structure of argument are likely to be active in the skeptic community and therefore potentially familiar with the term in its older sense.
