Successfully monetized then. We can play semantics all day, but Facebook has lost a shit ton of money and has no plan to make a shit ton + X(billion) in the near future .
There is a huge difference between a -$300M run rate and a shrinking -$150M run rate. Monetization isn't always about turning on one big switch, but about turning on lots of little switches.
Remember, Facebook makes -tens of millions- of dollars on people sending a picture of flowers to their friends. There are plenty of other opportunities for Facebook to make money, they're just making sure to do it right. MySpace is profitable - then again, who is on MySpace anymore?
It matters completely, if Facebook can't get a plan together to make tons of money there won't be an IPO to bring in the fuck-you money. Right now they are unprofitable and have no great outlook that would lead to an IPO.
