Each of these language homepages clearly explains that they are introducing a programming language. This new racket-lang.org page doesn't. It has a huge impact on what users will think when they load the page.
The PLT Scheme homepage is leagues better than the new Racket one because it tells me exactly what it is for. Don't let yourselves go backwards.
https://www.rust-lang.org/ is the best example. There is a code example, clear links to documentation and source, a concise description, easy to see links to most common places. Very, very good.
From what I saw, it looks like a site that helps you make a variety of line drawings. Next time I need to make some line graphs, I'll check it out.
