Creationists also don't believe in anniversaries.

PZ Meyer on an old argument with a creationist, trying to use pseudoscience to trump science.

I was just reminded that last year at this time I announced an anniversary. In March of 2004, I critiqued this mysterious abstraction called "ontogenetic depth" that Paul Nelson, the ID creationist, proposed as a measure of developmental and evolutionary complexity, and that he was using as a pseudoscientific rationale against evolution. Unfortunately, he never explained how "ontogenetic depth" was calculated or how it was measured (perhaps he was inspired by Dembski's "specified complexity", another magic number that can be farted out by creationists but cannot be calculated). Nelson responded to my criticisms with a promise.

On 29 March 2004, he promised to post an explanation "tomorrow".

...

On 13 January 2005, he told us to read a paper by R Azevedo instead. I rather doubt that Ricardo supports Intelligent Design creationism, or thinks his work contributes to it.

Ever since, silence.

I'm sure he is just waiting, to build up anticipation for his earth shattering...thing. That must be it. Brilliant.
