Actually, that’s not true.
I run a single user Calckey instance (@thoralf@ck.umrath.net, moved from a single user Mastodon instance) and it works just fine. The only difference: The local timeline is just me.

Webpages that could get created in 5 minutes without a super fancy editor and excessive coding - good times!
The content is also no problem:
Both will fill the global timeline quite nicely.
