From reading some of the stuff Yahoo put out back in their prime. I always got the sense that they thought they would never fall and were maybe a bit invincible.

I think Zuckerberg and Facebook in general, are very aware that Facebook is on the decline, they need to diversify. That's why they bought Instagram and used it to flight Snap. That's why they spent such an insane amount on WhatsApp.

Zuckerberg knows they need to create or acquire the next big thing to make it in the long term. At least, that's what it seems like to me. I have a feeling they aren't going anywhere soon because of this.
