Reddit Migration

This question may be moot but it's something I've been thinking about. I've only recently jumped into this brave new world so you'll have to forgive my ignorance.

I'm wondering if there's any etiquette or conventions for which instance a 'migrated' subreddit should be hosted on. More specifically, I'm thinking about the communities where the subject matter is more regional.

For example, if I use an account on a UK-based instance because that's local to me then it might not be optimal to create a community on the UK instance if the subject matter is US-centric. Would that ultimately lead to a worse experience for the majority of those community members that are based in North America?

The difference in speed for me connecting to something in the UK vs the US is basically negligible, but it's non-zero and potentially exacerbated for those that have slower or unstable internet connections. This may be particularly true while rapidly-expanding instances are a bit unstable anyway.

It's obviously up to the mods of each subreddit to decide what to do for their "official" migration. However, what I'm afraid of happening is:

1. A migrated subreddit is hosted on an instance which has a detrimental effect on the experience of a significant number of its users.
2. To combat this, former Reddit communities get splintered into multiple, region-based communities.

The latter wouldn't be so bad but one of the things that made Reddit so appealing to me was the differences in perspective from all walks of life that sparked discussion. That sense of being part of a diverse, active community might be lost if the overall Reddit migration is handled in a haphazardly way.

Does anyone have any thoughts on this? Am I worrying about a non-issue?
