Tamas, As someone who has used Python for two decades and Julia for about 2 years, I can appreciate what you are saying. But I just simply disagree. Perhaps Racket might be more appropriate, at least Racket is designed for pedagogy. But even so. I think a sample application solving a non-scientific problem would be particularly useful to this community, especially for on-boarding those who are using Julia as their first language. A MUD pops out at me because it can mix in creative writing and other artistic assets. Making stuff fun is important.
