I haven't done a careful analysis. However, it is my distinct impression that the same thing has been happening on the usenet group talk.origins as we see here. That is, the number of creationist debaters is way down from what it had been.
I'm not sure why that change. My guess is that the fundies had been putting their hopes and efforts into the ID movement. After their Dover debacle, I presume they will regroup. We should expect a change of strategy.
Impeach Bush.
