Interesting pattern emerging, the IT time of the admins is pretty damn priceless, (thank you admins!) and when an instance gets up to scale a lot of them can end up with a hard cost of 10 cents per user per month.

The last stat I remember from Facebook was revenue per user per year was around 4 dollars. At 31b revenue and 2.7b monthly users, Youtubes average profit per user is about $10 per user per year. 100 million people pay for YT premium now.
