The lesson
Describe the product by how it feels to use, then put the quick next step before the longer read.
The post reads "We're excited to introduce: Linear, the issue tracking tool you'll enjoy using.", then a vision sentence, then "Sign up for early access at: linear.app". A second line points to a Medium announcement. The attached link card, from linear.app, shows a white logo and "Linear" on near-black, captioned "Linear – The system for product development".
The sentence "Our vision is to create more enjoyable and efficient way to manage software development" is generic and could be about anyone. Keep the feeling-first positioning and the two ranked links.
