Just a tip for any new developers in the Fediverse space:
If you're making any sort of "search" function to browse Fediverse posts, make sure that it respects people's "Discoverability" settings in the Mastodon software.
This might not be the easiest thing to do.
However, given that 73% of people on Fediverse are interacting with Fedi strictly through Mastodon, you don't have much choice.
If your project gets widely known and you're disrespecting people's privacy options, you'll be highly vilified and probably Fedi cancelled.
