The long tail of social networking

I'm in the throws of reading Chris Anderson's book, The Long Tail, a story of an Australian bush kangaroo - kidding, OK? - and got to thinking that a power law may exist in the world of social networking. Such a power law (1/x) may show up in the amount of time spent on SNS activity and the threat to a business as a result of SN activity may follow a similar power law. For example the threat to a business of the most dangerous post is twice as much as that of the next most threatening and three times that of the following etc.

Not sure if this will go anywhere but thought I'd jot it down anyway.
