That's how this reads now. I had to read the GT page a few times before realizing it was a development environment for Smalltalk, specifically.
In general people who use a lot of buzzwords ('opinionated', 'beautiful' 'reactive') are trying to impress other developers already in their space. The more they use, the more alienating it is to interested general reader who doesn't have time to parse all this social coding and just wants information about a new topic.
This project looks great (for people who use Smalltalk), but the text does a poor job of communicating what it does and why you might want to use it. Even if you want to write a technical blogpost that gets into the weeds, there should be one plainly written short paragraph that summarizes what it's about for the first-time visitor who has no prior context.
