Economics is supply/demand.

I would focus on investing, particularly defensive investing.

If you want the easiest allocation possible put some portion of your paycheck in an S&P500 fund and in 40 years you should have enough for retirement.

Good luck!

Whatsapp had 1B users with far fewer eng, why is Twitter so big?

Here is my back of the envelope math of how big I think the company should be for their main offering. Over the past years Twitter has acquired a ton of companies, but I'm going to leave them out of this equation.

Eng (250)

===========

Backend/Storage: 100 eng

Subscriptions: 50

Front-End: 50 eng

iOS App: 20 eng

Android App: 20 eng

UX: 10

Abuse/Moderation (200) ========================= Abuse: 100 Moderation: 100

Marketing/Sales (210)

=======================

PR/Marketing: 30

Ad Sales: 180

Mgmt/overhead (40)

=====================

Legal/GDPR/compliance: 20

HR/Recruiting : 10

CEO/CFO/etc.: 10

What do you think? How far off am I? If more people turn to subscriptions perhaps the abuse/moderation team will shrink in the future.
