Only Lemmy.world and Lemmy.ml got defederated as far as I know. I see you’re not on one of those, so you can still see and participate with them.

They make very nice audio mixers.

The Memmy TestFlight is full at the moment, but should be on the App Store soon. I highly recommend it.

Mlem and wefwef started good, but imo, they’re not there yet. They both look good, but are still missing a lot of my preferred functionality. Development also seems slow compared to Memmy too, but Memmy’s dev is also a machine pumping out updates every day.
