In THEORY, the #ActivityPub #Plugin for #WordPress is a wonderful idea.
In practice, I have not seen it actually work even once.
I'm able to find my WP user from here in the mastodon.hams.social web UI, and can "Follow". But it doesn't show my headshot AVI - a plain WP logo instead.
Then, after doing said follow, I switch to WP and make a post. Come back here - do I see that post? Hell no.
So I DM from masto to WP. Does that DM show UP anywhere? Nope.
It dances around the edge of working.
