Thanks for the great info posted here! That said, one small nitpick: I'm fairly sure Facebook does less revenue/user than you do: They have a billion users, and did (order of magnitude) 5 billion last year: That's $5/user/year. Which you do per month. Still, it's amazing you can provide this unlimited service for that small fee!
