[Python-ideas] Keeping discussion relevant

Sometimes I see threads briefly go into topics that are unrelated to new features in Python. For example: talking about a writer’s use of “inhomogeneous” vs “heterogenous” vs “anhomogenous.” We get what the original author meant, there is no need to fiddle with the little details of language at this point, even if it is fun. These extra emails, though harmless, impose a visual, time, and navigational burden on the readers of the thread. It’s okay if the problem is little but not if it’s big. Two questions: How often does off-topic discussion occur? Does it need to be find ways to reduce the amount? How can we find ways to reduce the amount?
