It's better than I expected tbh, the app I use is Jerboa (it's suspiciously similar to boost, I'm waiting for Ruben [the dev] to publish boost for lemmy)
Everything is done right to ensure an open platform and that another redditpocalypse doesn't happens, the only thing that concerns me is that if I choose lemmy.world, I'll miss on other things, I just need all my tech related and videogames (and blender) subreddits to migrate so I fully leave reddit.
Also, I think I got a good username
What if he makes a boost instance? He seems like a normal person, with some background and proved interest in user experience
