19 subscribers came from my Notes. Not one was matched to the exact Note that converted them.
The data showed the channel, but not the content.
That gap is why I started Subshack Growth: to separate attention from growth and document what the numbers actually say.
Here you’ll find:
• Real experiments run on my own publication
• Verifiable metrics including failures and unknowns
• Practical playbooks you can test
You won’t find subscribe-for-subscribe, auto-posting, bots, or invented attribution.
