Also, some quibbles about the article. Anything one writes, such as a contract or blog post, is automatically granted a copyright. Also, the blogger seems to think contracts are some sort of public reference like a statute. They are not. While you can find form books (private), contracts are drafted by lawyers for their clients and are private property.
The author's one interesting idea is a software-type patent on contract clauses. If you could patent, say a non-compete clause, well, that would certainly transform the legal world. I don't think it is feasible, though, and shows the folly of software patents.
