I am sticking to my theory I posted in April.
1. URL+initial Title has more importance on kw, just try a longtail kw and see.
2. Internal link juice is greatly diminished.
3. "fresh" content sites on steroids - has gone overboard with adding link juice internally as can be seen by sites like ezine, associatecontent, squidoo, etc.. ranking absurdly on so many terms.
4. additional logic added to site structure to determine site classification (you selling something or reviewing it, better not try to both, get lost in the wash).
Just some small observations.
