The article has the merit of significantly reducing the size of the original essay, while IMO still retaining two strong messages:
1. The original (is it?) method used to prevent spam, and
2. The 'seed' factor, which is expected to make spammers work harder. At mid-page I was thinking "meh, spammers will just have to improve their writing then", but this may not be sufficient thanks to the user-specific seed.
[edit: I didn't realize the original article was from 2002. I agree the article is a bit obsolete at that point.]
