Not hard to imagine. 700M users at a $70B valuation = $100 per user. I guess that's why how the current valuation of LinkedIn comes about. And if you use this metric, and believes that LinkedIn's growth potential is significantly stronger than Facebook, you could even argue that LNKD is still way undervalued.

BTW I made a Tagxedo (word cloud) of this morning's LinkedIn News, and one prominently featured word explains all (the word starts with "F" and ends with "k" :D)
