After more sites use the author tag - which is an "authority signal" - then the whole concept becomes more viral.

That's great for a blog or a newspaper, but when it comes to UGC content such as review sites they're all original authors so which one do you pick, Yelp? or just build your own Google reviews and toss 'em all out?

FWIW, Google can't tell who the original author of a document is when they host it in their own Blogger, and it was written in 2006 and still in blogger, and gets scraped in 2010. The 2010 scraper wo, so author tags are the least of their problems.
