"The use of the product grows the product. If I'm using PayPal to send $1,000 to somebody, there is no way they will not create a PayPal account to accept that $1,000."
Zero marginal cost — each user invitation scales infinitely
Network effects compound — the more users, the stronger the product
Faster than paid acquisition and healthier unit economics
Works best when product use inherently invites others to join

How Products Invite Growth
Network Effects
Telegram, Discord, PayPal — the product requires inviting others to deliver value back to you. Compounding effect.
Billboarding
Calendly, Dropbox, GoFundMe — you must share your link or content to use the product. Every share is a marketing impression.
User-Generated Content (UGC)
YouTube, TikTok, Reddit — users create public content that surfaces on Google/social, bringing new traffic naturally.
The power questionCan you build product-led acquisition into the core action users take to get value? If yes, you've found the growth engine.
Building State for Retention
Make Users Too Valuable to Leave
Non-transferrable reputation: eBay sellers with 10,000+ ratings won't switch. Their trust is locked in place.
Audience graph: YouTubers can't take their 1M subscribers to Twitch. The audience is platform-specific.
Irreplaceable data: The more history you have (emails, messages, memories), the harder it is to migrate.
Compounding advantage: Early users' investments compound over time, making switching costs exponential.
Why eBay & Craigslist Win
Despite terrible UX and no innovation, they're unbeatable because sellers have invested years in reputation. Switching means abandoning trust equity.
The exception
Substack lets users export their email lists. This hurts retention but builds loyalty and is better for the ecosystem.
Writing & Novelty
The Creativity Faucet
Bad ideas must come first — they're the only path to good ideas
Don't stop at the first "gold" — that's just the obvious surface idea
Novelty is what catches people — you want original takes, not curation
Quality followers > volume followers — one true fan is worth 1,000 labor followers
Building mind followersWrite original insights, not fortune-cookie threads. Mind followers have higher affinity, loyalty, and will convert when you ask them to do something.

Myths About Growth & Content

✗More followers = more powerINSTEAD →✓ Follower quality matters more than volume. Labor followers unfollow; mind followers convert.
✗Novelty kills growthINSTEAD →✓ Novelty IS growth — people follow you for original takes, not curation. Paul Graham never wrote threads; he wrote original ideas.
✗You must finish creatively in the momentINSTEAD →✓ Good ideas come after bad ideas. Sit with the discomfort; the gold is on the other side of the blank page.
