Facebook Valuation - What the f@ck

I was browsing through Sky News, yes I was reading the news. What caught my eye was Facebook's valuation after getting an investment 322 million from Goldman Sachs. How does 322 million convert a business valued at 1 billion to 32 billion. This just not make sense and why if a company originally valued at 1 billion need an etra boost. 


On the other side what a wonderful feeling being an investor with some shares in Facebook. You shares just increased by 32. awesome. 


Please read in more details: Sky News


If you were Facebook, what would you do with 32 billion? Which companies would you buy...Twitter? Ebay? Yahoo? 


Oh to be that powerful....
