Instead it could really use a lot more explanation on how it works. If you make comparisons make sure they are fair. The image "JavaScript mixed together" and "Strict separation of concerns" is just comparing apples with oranges. Multiple times in the docs it compares a huge complicated JSX like component and replaces it with 3 lines of html and 3 lines of css. I don't believe that it does the same thing.
Some of the claims are strange. It praises standard HTML but apparently you have to use some custom Markdown syntax to write it. How does that add up? And on top of that it also introduces new syntax for loops and variables.
This could all work perfectly fine. But my suggestion would be to talk more about how it works and what are the advantages and less trying to bring down competitors. It could use less grand claims and focus more on what it really does.
