Put like this, FB got a steal.
I really did not get the purchase at the time, I thought FB had got caught up in it's own pre-IPO hubris. It was one of the reasons I did not buy.
Seems I was wrong. Again.
Let’s look at this another way. Facebook offered a deal worth $1 billion to buy Instagram once upon a time. But when that deal closed Facebook’s stock had lost value, and the little photo app was picked up for a mere $715 million. So, Twitter lost 12.14 Instagrams in value today. Investors like growth, and Twitter didn’t have enough.
