as long as the community is created on a larger instance it should show up when users sort by all within that instance
This is an issue for communities that are on smaller instances, and with the current algorithm it's like a brick wall trying to break through to feeds of users on the big instances. For example, the most active college football community is !cfb@fanaticus.social but the abandoned community on lemmy.world keeps gaining subscribers (even with no content).
As a whole, niche-driven instances (e.g. sport, film, literature, aviation) and geography-focused instances (e.g. midwest, dmv) just aren't gaining much traction.
I watched four films this week, all of which I'd seen before (so clearly I quite like them all):
Really tough to choose one, but would probably have to give the nod to Mr Smith. Jimmy Stewart is just too good.
