Two Billion Dollars

Negotiating mostly on his own, Mr. Zuckerberg had fielded Mr. Systrom's opening number, $2 billion, and whittled it down over several meetings at Mr. Zuckerberg's $7 million five-bedroom home in Palo Alto. Later that Sunday, the two 20-somethings would agree on a sale valued at $1 billion.

It blows my mind that people throw around numbers like these. "Yeah I think you're company will be worth two hundred billion dollars one day so by my calculations one percent of that is two billion dollars thank you very much."
