I can't tell you how many times I was steered into, and avoided, Google plus.
Travel - guilty
Hotels - guilty
Insurance - guilty
It's trickling downwards at an accelerated pace, nothing is safe from being more than just *ranked* by Google anymore.
You needn't look much further that the recent quarterly report in which Google enjoyed a MASSIVE increase(30%+) in earnings from their affiliate efforts when many(most?) webmasters began living a Panda and Penguin induced nightmare.
You have to call it like you see it. My concern is that the investigators are sure they will be finished by x date even before cracking open the files, it stinks of a pre determined decision ya know? Either way, I hope this resolves the issue one way or another so that we can all continue to create websites without fear of Google assimilating the content instead of just ranking it.
