A community or game which is just people writing/trading short scripts?

I want to be part of a community of programmers or scripters, where we write up and comment on each other's programs.

Ideally I'd like it to be blend which is heavier on the writing and the discussion than I usually see posted.

Example of the pure programming side: Leetcode, which definitely gets the programming side down, but it's a little dry for me, and the community, while present, seems less integrated.

Kaggle's pretty close.

Unfortunately, I wouldn't say either are very "fun."

Something that hits all points - discussion of scripts or short code snippets, writing of code snippets, adaptation of other's code snippets, AND fun - would be ideal.
