It's funny, I remember discovering the Keto diet 10 years ago on a small but passionate subreddit. I tried it and lost 20 lbs, it felt like a magic diet. But all my friends thought it was super weird.

Fast forward 10 years, and it is totally mainstream! It's a good lesson to remind us that if something gets a small cult following online, there's a good chance it will take off and become huge. Just takes many years to become a reality.

(I'm not Keto, this is more of a lesson in markets and business)
