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.

IAMA was the subreddit that hosted AMAs.

Both acronyms come from the titling format: “I am a XYZ, ask me anything”

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.
