Good observation on the "where to post this?" challenge.
I've also noticed that some of these posts are copy-pasted into other (specifically Android) Slack workspaces verbatim, so I wonder whether the implied association between Android and Kotlin - with many juniors thinking that Kotlin's only purpose is for Android development - adds to the problem; Python is known more as a general purpose language, so doesn't have a strong association with a particular platform, whereas most people, certainly those early in their development career, will have only heard of Kotlin in an Android context, so the boundary is more blurry.
