Fediverse

Strong ideologically driven instances may be more invested in spreading the gospel, so depending on the frequency of posts that populate /c/all and topics that garner a lot of attention it can lead to certain instances standing out compared to more generic ones. It's kind of becomes like someone sporting a sports jersey versus others that might just be more generic clothing as an example.

Maybe better example might be like how people assume things by the bumper stickers people have on their cars, or signs and flags they choose to display in front of their houses compared to the general neighborhood. There's some passion that may be assumed.
