Hey carian,
thank you for joining here and asking!
I can’t give an example with mastodon, you should ask the mastodon people then.
But many people tried several times. The same about ActivityPub Conformance and the Client2Server portion of ActivityPub for mastodon.
I point to this instead
What Jejune Is, Why Jejune Matters
by @kaniini
and this
And as more people encourage
@rubenverborgh and @aveltens to have at least a 1hour meeting with ActivityPub people as better.
I would join anytime cause it is a matter of priorities. Anytime, even in the middle of the night.
