exactly my thought. and here thr reader view of FF is a godsend.

having 'accessible' content is not only for people with disabilities, it also help with bad color taste.

well, at least bad taste for readable content ;)

The FF reader view here starts from "We just saw how a Decision Tree", gobbling up half the article. Simply disabling CSS works better. Though in both cases, it seems that ordering might be a bit mixed up.
