Controversial but intriguing take by Matt. Generally someone I admire so shouldn't reject this part of the story before I do further research.

Concept of Voice vs Exit. Voice - try to change/modify the system itself. Exit - quit the system, go or start an alternate one without constraints or locks. Crucial element of democracy is to reduce the barrier to exit. 'Giving people a way to escape influence of bad policies on their lives without getting involved in politics'.

Warren Buffett talked about gambling in stocks -
Speculators may do no harm as bubbles on a steady stream of enterprise. But the position is serious when enterprise becomes a bubble on a whirlpool of speculation. When the capital development of a country becomes a by-product of the activities of a casino, the job is likely to be ill done. - John Maynard Keynes.

Earlier Buffett showed a report of top 30 companies from 1989, none of them made to top 30 of 2019. He also talked about early 20th century where many people predicted automobile to be the next thing and indeed it did become one, but he pulled out a list of over 2000 failed companies from that time in the sector showing that stocks are way more than just predicting the next big market.

Retention is the single most important thing for growth.
- Ideally if you have a asympote to x-axis for retention curve, you have a product market fit for that set of users.
- Look for Monthly Active users - I think in Atlas' case we should use WAU.
- What is a good retention? - Figure it out for yourself. DO THE MATH. Different verticals need different retention rates - have to tools to think about it.
- Should look at the number that actually matters - In Atlas' case that number should be no. of cards saved per user/week. The users should also be segragated into further groups according to their personas and ideally have atleast 50 people in each persona for analysing the data.
- What's the magic moment for Atlas?
- For people who are already using the product all the time, notifications probably won't do much harm, let them take control if they don't like them, but don't miss not sending across things to marginal users.
- Growth in pinterest's case was driven by marketing.

- Virality 3 aspects - Payload, Frequency and Conversion. Conversion is what actually matters for virality.

"If you are not embarrassed by your product release, you've probably released it too late."
