First Major Endorsement - drove $1.6k in presales

I sent Dan Abramov a preview copy and he publicly liked my book: https://twitter.com/dan_abramov/status/1265463366694440960?s=20

This drove 800 followers to the book's twitter overnight, 300 to my own personal twitter, landed me 42 more prelaunch sales at full price. And i have a nice endorsement for the landing page.

Influencers. Can't live without em!
