You remember Friendster, right? No? It is a social media cautionary tale about hubris and taking the money while it's good.
Friendster was one of the original social media networks, long before Facebook, and in 2003 they were offered $30 million in pre-IPO Google stock and in 2008, a year before it sold for under $30 million, Friendster turned down a $150 million buyout. The Google stock would have been worth $200-800 million. Basically, it was run stupidly. When you get acquired by Kuala Lumpur-based MOL, a payment systems seller heard of nowhere outside Asia, you have fallen far.
