the term “cake day” just makes me think of r*ddit. I’ve seen Lemon Day going around, but we probably want to avoid affiliation with lemon party.
not that we can tell anybody what to do anyway, and each instance could even have its own. anyway, it needs to be something that obviously means “anniversary” and doesn’t require explanation otherwise it’ll just be annoying
Given that Lemmy’s mascot looks like a mouse (I think it’s technically a lemming), an idea that came to my mind was “cheese day”.
