Always love your work, Lex, and enjoy the listening, immensely.<br>But you dodged the topic of sm critic completely, almost like there was no issue there. I can understand Mr.Systrom reluctancy to negatively speak to the work of Mr. Zuckerberg or even hint at it's negative impact on fb users. There's a lot there that you wouldn't dare touch in this conversation, for ex. Zuckerberg is disliked because he failed to deliver what he'd set to do: connect between people, and in a positive way. i.e. Harmonize. This is why fb gets harshly criticized. You admit yourself that fb is not what it's been earlier, and that you aren't sure what fb's about anymore. I believe like yourself in the goodness of people, and I believe Marc and Kevin authentically believe what they do benefits people. Too many users think otherwise and got a good reason for it. There may be ways to fix fb and Instagram, the answers however, cannot be left to the hands and minds of engineers and less so in the hands of business people.
