Debunking Corner - Weasel Words Again

From here;
Over at uncommon descent William Dembski is musing over Richard Dawkins Weasel program. Why you may ask? Way back in prehistory (the 1980's) Dawkins wrote a little BASIC program (in Apple BASIC of all things) to demonstrate the difference between random mutation and random mutation with selection, which many people were having trouble grasping. Now, this wasn't a simulation of natural selection, and Dawkins was very careful to point this out.

But as a demonstration of selection versus simple random mutation, with the string "methinks it is a weasel" being selected in a matter of minutes, when simple random mutation would take longer than the age of the Universe, it was pretty stunning. As a result, creationists have been having conniption fits over this little program for decades. Such is its power, the Issac Newton of Information Theory, William Dembski, spent a not inconsiderable portion of his time attacking this toy program. In particular, he claimed that after every successful mutation, the successful mutation was locked into place, and couldn't be reversed. But he was wrong, and it seems he just can't admit it.
