Sure. It's not hard to construct all kinds of failure scenarios for FB. I just don't think that crude averages are much use here at all.

In general I think that an average just isn't a very useful statistic. It throws away way too much information.



It would be interesting to note what the standard deviation is on those figures. My guess is it's quite high, which does give Facebook a bit of breathing room.


I'm surprised how often a mean is quoted without a standard deviation. Especially in an analysis like this. It's only telling you half the story.
