eldavojohn writes "Think that Goldman Sachs spent too much on Facebook with the $450 million investment? Well, a very wealthy customer of theirs decided to leak Facebook's financials yesterday after receiving it over lunch: '... during the first nine months of 2010, Facebook generated $1.2 billion in revenue. Net income at the firm was $355 million. The financial statements were not audited and offered little detail about how Facebook generates its revenue, said the source, who did not want to be identified because he had signed a non-disclosure agreement.' Expanding this nine-month period to a year yields $1.6 billion in revenue and under half a billion in income. Given that, should Facebook be valuated at $50 billion?" Reader frontwave adds news that other social tech companies are hurriedly considering IPOs of their own.
