Google exposes search algorithm secrets

1. GOOG promises(?) to "expose search algorithm secrets".

Nothing earth-shattering has been exposed [like MS promises to be interoperable and open, see OSL and ODF support...]

2. Nobody ever said, that what you see is what you get from them [like search results given by exposed algorithms]

fwiw, i think explaining each move after its been made and progressed from is a fantastic idea.

Finally Google grows enough to explains his own concepts.
