this constant tweaking of the algo
Seems to me that the tweaking has at least three foci:
1. Understanding user intent (relevance)
2. Understanding concepts (relevance)
3. Fighting spam
We hear a lot about the spam fighting. Not so much about the relevance tweaking.
So, panda/penguin fight spam. Fighting spam does not make the SERPs any better. Right?
