@gbhnews A case to make for the business types, too - for an organization, having an instance with a domain name is the blue check of the Fediverse. Since you're on mastodon.social, you could be faking. Probably not, but you could be.
In addition, you would have the sweet traffic metrics, directly, that your bean counters so earnestly desire. Having accounts per-show would segment your metrics appropriately. There's really all kinds of wins to be had here.
