You know what I love about the Fediverse?
I don't feel compelled to follow everyone I interact with. My "algorithm" is the timeline I have made for myself, as contributed to by the people I have chosen to follow.
Many interactions are just two ships passing in the night, and that is it. Sometimes, we pass again and I choose to follow. Sometimes, I don't.
But it's not like I have lost all chance to ever see this person again. The algorithm of commercial platforms emphasizes following all interactions, no matter how ephemeral. Because anyone you don't explicitly follow may be lost forever in the soup of populist commercialization.
