Why it matters for customer discovery

- Useful when your ICP lives in creative or identity-driven communities rather than r/SaaS.
Best for
- Creative and design tools
- Fandom and community products
- Personal storytelling and reviews
- Niche aesthetic trends
Weak for
- Enterprise B2B devtools
- Formal B2B procurement signal
- Technical API debugging
