I think that the more people that move to the Fediverse the better. As it gets popular Lemmy will be more and more populated with instances that can be curated to the user's wants. Don't like how one instance is running things? Move to another. Don't like how one community does things? Move to another. The more popular Lemmy is, the more options Users will have.

I would for a few reasons. Particularly to show the world that we don’t need corporations to create something good.

Though I am worried about some inconveniences caused by the fundamentally separate instances. Simple things like copying a post, navigating back to your instance, navigating to the search feature, searching for it, waiting for the result, opening the result and then finally able to take action on it.

It can also drive disconnection, despite trying to work against it. It has the ability to put people into silos and build social walls due to intentional and unintentional ignorance. Though you can most certainly argue that is already an emergent property social media algorithms today.

I'd like it how it is now but a bit more active, like reddit circa 2008 when I first joined. Sure there were memes and shitposts, which are fun and have their place, but even then the discussions on news stories and other serious topics were of unusually good quality. Tildes captures the later quite well, but is also pretty quiet.

I think in the future people will care much more about free software and privacy, so it's inevitabile that federated platforms like Lemmy will be mainstream. Reply: I would like enought people to have more quality contents so that I can drop Reddit. Also more people means more interest and at the end a better software.

I want it to become as useful as reddit was in finding concise and correct information for a huge variety of topics.

The great thing about Lemmy is that there's no admin, no one site, no single set of rules everyone has to obey. So Lemmy becoming mainstream doesnt necessarily mean everyone tolerating a new culture. Niche communities can continue to exist, instances can isolate themselves if they want and turn off registrations, "eternal September" isn't really possible on a network like this.
