The number of people you want to follow is much smaller than that 0.1%.

Granted, not everyone I want to follow is on Mastodon, but many, many people I do want to follow are. More than I have time to follow.

Ultimately, the constraint is my time - not the percentage of folks using Mastodon.

(And there's also the bridge with BlueSky, but it requires the BlueSky account to actively consent to the bridge).
