Interesting ideas.  Thanks for sharing them.

I think that Google is talking a lot about this as a "quality website update"... and that is getting them attention in the media but it is also kicking a lot of webmasters in the butt to clean up their websites.

I think that google should make a "content registry" where I can submit my content and say "this is mine" and then copies or spins of that content will not get traction in the SERPs.

And, I think that they should take a closer look at websites in the Adsense program because the ability to monetize crap and theft is driving lot of bad odor in the SERPs.
