It is good that Penguin is here among us by now. My site did not get affected by this which makes me happy and strong as i was not doing anything spammy. Yesterday i come across a article which states that Google will change its ranking system and the result will be based on complete information but not on keyword ranks.

What can you figure out with this. I think Google will focus more on Ads and +1 from sometime. Have a look.
