Pushing cold blog readers to try your tool rarely works.
So you need a transitional CTA, something that worms them up.
But it needs to be aligned with the goals of the reader.
And I think pushing folks to a community discord is a solid option.
I like the copy "Discuss this blog on Discord" as it is very reader-focused.
Some folks read the article and have more questions.
They want to discuss it somewhere.
And while you could just do a comments section, a community gives you more options to get people closer to the product.
