TheMadScientist your right about one thing what you said makes no sense at all. How do you know with Caffeine there isn't any algo change. I don't think you were around with the Big daddy but thousands upon thousands site tanked and yes there was an aglo change for it as well.
Won't effect your ranking please don't try misleading people by making this kind of statement.
Truth is non 0 nada of us have a clue what's changing we are all watching and trying to understand what IS changing.
