Very cool, if true

There's an error in the Facebook data storage piece (ironically published on Livejournal): 3 billion people a month use FB, and it spends $30Bn a year on infrastructure ... but there are only 0.33Bn people in the US: realistically, the USA accounts for about 200M users, around 5% of FB's usage. So if it was run as a public service the cost to the US government would be closer to something on the order of $1.5Bn a year, which in US government terms is peanuts -- less than the production cost of a single SLS rocket or B-2 bomber.

(The point about it being private and very dangerous still stands, but it's annoying to see such an obvious error in an otherwise solid argument.)
