I didn’t really feel this was about the inside story of Instagram—it was more 50% cultural impact and 50% Facebook. Truly, I learned more about Zuckerberg and Facebook corporate culture than anything about IG. Interesting all the same as it continues to confirm his creepy megalomaniac status, but not what I wanted to read about. And who edited this book? The comma usage was crazy, sometimes requiring multiple reads of sentences since they were so mutilated by shoddy punctuation.
