Wireless is super convenient but I hate all the micromanaging that needs to be done with batteries. Lithium batteries has made this generally better but there's still a lot of subtle ways that batteries like to change when you aren't looking. It's fine when you only have 1-3 batteries to deal with but it gets tedious quick as you end up with more and more batteries.

I think the beauty of a community-of-communites platform like Reddit/Lemmy is that we can have both in a way. Sub-communities should be encouraged; where high-level communities can grow for the increased engagement and content while sub-communities can remain small and connected.
