Just in case people didn't know, you have to opt in if you want your posts to appear on your & other server trending posts pages.*
To opt in go to settings & select public profile, then select privacy & reach. Check the box Feature profile and posts in discovery algorithms.
*Not all servers have their trending pages on display to the public.
Trending depends on a minimum number of interactions with each post. The exact number varies depending on server size. #InfoToot
