I don't think so : in mastodon, people knows they can federate. After trial and error process, they choose their instance based on reliability, moderation and the topics inside.
I think lemmy/kbin will follow the same path.

i created a lemmy community about backpacking 3 years ago, at the birth of lemmy : only 3 users! Since one week, there are much more post and comments. Thank you reddit ! i love you.

i think you take a wrong decision : i appreciate beehaw, but whatever you will do, you can't control everything let people use 'block user' feature, that's the purpose of this feature, and focus only on what people report as 'bad user'. Defederate for a toxic instance as 'lemmygrad' is good, but defederate from lemmy.world makes no sense for me. i hope it's just a temporary decision

During 40 years, everything has been done for cars. But it's ridiculous to use a 5 persons transport (car) for only one person. The ecological problem is not only thermal vs electric, it's also cars versus 2 wheels transport

i miss some reddit communities, but for a basic usage, lemmy/jerboa replaces reddit without problem.

there is a trend now : big $ don't want 3rd party apps any more. May be the next is youtube : block individious, block newpipe...

i wonder if all this big social platform will not end with lots of fake profile feeded with chatgpt. For your information, I'm NOT a chatgpt comment 😜

well, i don't want to be rude, i'm not communist or capitalist, just an average guy and i respect every political views, But when your alias/name is 'communist', i think you just obtain the opposite of what you want. I agree with you : federation is missunderstood and if people doesn't want an instance with political bias, they can choose another one.

a few days i use jerboa daily : it's not perfect but i can deal with all the restrictions

But i really miss an option to make all post as 'read' with a single button Just a suggestion for the next release. Thank you for your great work

well, you know that chatgpt becomes more and more human because i know lot of people repeating always the same jokes 😁

i would never watch youtube if i cannot use newpipe : as soon as youtube blocks newpipe, exodus to peertube may happen

The possibility to follow hashtags in mastodon is a real progress : i just follow a few account but i like following hashtags on mastodon/pixelfed and may be tomorrow peertube. lemmy suffer from lack of contents. I hope it will improve in the comming months
