This seems to be the case, which makes FB's acquisition very smart. Instagram seems to be, from my anecdotal evidence and the heavy promotion I see of it on Tumblr, growing very rapidly. FB has nothing to worry about when they have one of the trendy "simple" social networks in their camp. However, I would find it disappointing as Mark Z. that the FB platform itself would be dying with the younger generation.
