Review of the two experiences:

With PieFed I can just keep scrolling without needing to click. Things just work and are where I expect them to be (based on pas UX experiences (reddit)) I can see way more content without ever getting confused or needing to click or make decisions, making me stay curious and engaged. Where as with Lemmy I very quickly got frustrated and confused, making me want to abandon ship and do something else, and I’m way way way more resilient than the vast majority of users
