The Unison language
One thing that takes away from programming languages is not having code samples on the index. I think this lets someone know immediately if it's interesting to them or not. Show a sample of code with the console output or a screenshot of an UI from the code. I think Racket had it right ages back. They would show everything from a web server, to other things. This is what major programming languages (with some exceptions) basically do and it gives a developer more information than any amount of marketing speak.That said, I had to dig in the documentation to find code, and it didn't seem as obvious cause the syntax is definitely different from what I'm used to and there's weak syntax highlighting.
