This is amazing! I am a Substack user. I have a weekly newsletter and reading this just made me even more excited!
This looks very interesting. Defintively will give it a try when the time to do outreach comes.
@jakob_greenfeld Love how you create products that people actually tell you they want. Keep up all the good work!
A measure of community engagement at launch. Higher means more people noticed and interacted with the product. It's a traction signal, not a quality rating.
Discussion threads divided by interest score. Above 0.30 is strong. Below 0.15 suggests the product got clicks but not conversation.
Categories come from the product's launch tags. Most products appear in 2-3 categories. The primary category is listed first.
The scores reflect launch-period engagement. Historical data is preserved and doesn't change retroactively. The build date at the bottom shows when the index was last refreshed.
