Building 100 Link Collections in 30 Days — Day 7: What I Know (and Don't Know)

The Challenge

I'm building Culink, a platform for curated
link collections (think Pinterest for useful
resources instead of images).

To find product-market fit: create 100
collections in 30 days.

Day 7 Numbers

What I know for certain:

• 22/100 collections created
• 200 visitors (Show HN + IH)
• 14 signups (7% conversion)
• 4 created collections (29% activation)

Topics: AI/ML, startups, dev tools,
productivity, economics, lifestyle.

Decent metrics for 7 days.

But here's the problem.

What I Don't Know

These numbers tell me almost nothing about
product-market fit:

I don't know:

• Which topics actually resonate
• Why people signed up
• Why most didn't create collections
• What would make them come back
• Who my target audience should be

200 visitors is too small to see real patterns.

14 signups is too few to validate anything.

4 creators? That's just noise.

The Temptation to Overinterpret

With small numbers, it's easy to see patterns
that aren't there.

"AI collections got more clicks!"
→ Or did they just appear first?

"People prefer browsing to creating!"
→ Or is the creation flow too complex?

"Tech people are my audience!"
→ Or is that just Show HN selection bias?

I could make up stories to explain these
numbers.

But that would be guessing, not learning.

What I'm Using ChatGPT For

ChatGPT helps me create collections faster:

• Suggests relevant resources
• Writes descriptions
• Organizes by category

It's good for speed and structure.

But it can't tell me:

• Who needs this
• What problems they have
• Whether this solves them

That requires talking to real people.

What Culink Does

Create collections by topic.
Share publicly or privately.
Follow other curators.

Early stage. Rough edges.

What I Need to Learn

Before making 78 more collections,
I need to answer:

Who curates content regularly?

• Newsletter writers?
• Developers (awesome lists)?
• Researchers?
• Someone else?

Why do they curate?

• For their audience?
• Personal organization?
• Building authority?

What's their biggest problem?

• Finding quality sources?
• Verification?
• Organization?
• Keeping it updated?

The Plan

Week 2:

1. Interview 5 people who actually curate
2. Understand their real workflows
3. Find common pain points
4. Pick one target segment
5. Build for them specifically

No more guessing.
No more interpreting small numbers.

Just direct conversations with real curators.

If You Curate Content

I'm looking for 5 people to interview
(15-20 min each).

If you regularly curate — newsletter,
awesome lists, research collections,
anything — I'd love to learn from you.

What you curate, your workflow, your
challenges.

Building in Public

This is Day 7 of 30.

The honest version: I have metrics but
no clarity.

The numbers look okay, but I still don't
know who I'm building for.

That's what Week 2 is for.
