All of this discussion is worthless without any transparency about the numbers (and I don't mean: FB's lost revenue). I'm still of the opinion that targeted advertising [0] (as opposed to context-aware advertising [1]) is a bunch of BS. So 80% of the traffic to Carousel came from FB, but how useful was it? Is there an actual drop in total visitors who spend money on products? And how is this across the market? Does this mean smaller companies are now getting a larger part of the interested people where as they couldn't pay for them before? Was FB anything more than a "pay us for traffic"-mafia? Is there any win for the tracked people, or were they just getting served ads for inferior products from companies that spend more on advertising instead of quality? I really hate reading these pieces without this information. It's really useless.
