01
what I mean by it
El Librero de Gutenberg grew into a Facebook community of millions. People shared quotes, books, poems, and posts every day. That proved they wanted what the page gave them in the feed.
It did not prove that the same millions wanted my newsletter, a specific book, or whatever paid offer I might create next.
That gap is why I care about proven demand. I want to know what people already do when they want a result, especially when the action costs money, time, effort, inconvenience, or reputation.
02
attention can fool me
I know how seductive attention can be because I have spent years around large pages. A post can spread because it makes somebody laugh, reminds them of a person, gives them a quote to share, or looks good on their profile.
That reaction is real. It tells me why the post moved. It still says very little about whether the person will open an email, join a group, change a habit, or pay for help.
The signal changes after the scroll. What does the person do when the next step asks something from them?
03
the signs I trust
Payment is the clearest sign because the decision has a cost. I also watch for repeated use, waiting for access, asking for an introduction, building an ugly workaround, switching from another tool, or returning to the same problem after earlier attempts failed.
Repetition matters. One enthusiastic message can be politeness. Several people making the same inconvenient move over time are showing me something stronger.
04
how I use the idea
Before I build the larger version, I look for the smallest action that requires commitment. It can be a payment, a signup with a clear next step, a second request to use the tool, or somebody changing how they already solve the problem.
A test should resemble the behavior I need later. A free download cannot answer whether people will pay. A waitlist cannot answer whether they will return after using the thing. I choose the action according to the decision I need to make.
The smallest action should answer a real decision. Continue, change the offer, find another group, or stop. I would rather learn that from behavior than spend months building from compliments.

trails from here
I am separating four parts that I used to compress into the same phrase:
Before those tests, niches helps me define the smaller group and problem I think I am serving. Proven demand tells me whether that boundary describes real behavior or only a clean idea in my head.
- Attention, receptivity, and demand: what each response proves and what it leaves unanswered.
- Costly movement: why time, money, effort, repetition, and inconvenience reveal more than stated interest.
- Supply gaps: how to tell the difference between an empty market and people searching for help they cannot find.
- Consequential tests: the smallest real action that can change what I build next.
