Honestly, I kind of hate it, but since Reddit is unusable, considering all the subs that have gone dark (presumably permanently).
I'll be honest. I don't like the Fediverse concept - the fatal flaw of decentralized systems is that sometimes centralized systems are great. Basically, reddit was ONE BBS style forum for everything, which was the killer convenience. Similarly Twitter was the ONE microblogging platform for everybody, which was the killer convenience.
Because the moment anybody can operate a service, everyone does.
Right now, I need to buy a car, I can't find a good Lemmy community to get advice from. Searching for 'cars' in all federated communities returns:
Leave aside for a moment that "Fuck Cars" has 34x more subscribers than the biggest Cars community - there are two different "Fuck Cars" communities, and three different "Cars" communities. It's great that you have subscriber numbers, but there's no definitive place to find out information on cars. Reddit's CEO is right that Reddit was organized like a landed-gentry where a first-come-first-serve approach to the most popular forums was done, but that landed-gentry system solved this problem, whatever new problems it may have introduced.
Now, you could look for a technological solution to solve this problem: For example, you could have a centralized server for all federated Lemmies, some sort of "lemmyhub.com"
We'd all have to agree on it. People could set up alternatives, but we'd all have to basically coalesce and say: Yes, this is the thing we want. Maybe it'd use blockchain, I don't know. Point is, it's centralized and easy to find information. It would work "just like Reddit" where you would have ONE authentication/authorization that works seamlessly across all instances (the current system is anything but seamless), and there would be ONE key/value combo for keyword. So, instead of going to Cars@lemmy.ml & Cars@lemmygrad.ml & Cars & lemmy.world, you just go to cars.lemmyhub.com.
If you want to post, you just use your lemmyhub account and your post appears on the "default" community. You can still post on individual lemmies by going to the individual lemmy page as well, or by specifying which of your Lemmy instance accounts you want to post as.
Here's the problem with the merging all the cars communities together, though: There is nothing to prevent someone from creating Cars@NeoNaziHeartsFascism.com and spamming the community with bile or trolling. Lemmyhub could operate a blocklist for troll and hate communities and instances, but once you're doing that, you're making editorial decisions. And forget all the nasty ethics problems around "what's free speech/what's hate speech?" "what's acceptable to view/what's not?", you have legal liability problems if anything slips through the cracks.
Reddit wasn't perfect, and certainly they could have been more proactive with shutting down hate speech, and more speedy with shutting down illegal content, but by and large reddit worked. Reddit's authoritarian approach worked because it was mostly benevolent -- right up until the point that it wasn't.
So I don't think Lemmy can technologically make it's way out of the situation.
I think what needs to happen is a solution like the Wikipedia foundation; we establish a non-profit designed to create a centralized server which may choose or not choose to incorporate Lemmy instances. It runs on donations, not advertising, and it's not designed to maximize profit, only to keep the servers running. It would borrow heavily from the Wikipedia model in organization and structure.
Because I'll be honest - Lemmy and Mastodon are okay, but there's really nothing in them improving on the old Newsgroups system of the late 80s and 1990s. Reddit captured the market for forum discussions because it was simply a better solution, there's nothing in Lemmy that makes it better - for the user - than Reddit.
Should we then abandon Lemmy and go back to Reddit? No, of course not. Reddit, if anything shows us that eventually all authoritarian systems, no matter how benevolent they start, always eventually turn tyrannical, and can do so on a whim, and once they do so, it is impossible to get back to benevolence.
But I've been a redditor for 15 years - I predated subreddits, if you can believe that. And I'm not finding the things I used to go to Reddit for here on Lemmy - information, expert and informed discussion, and niche topics. Maybe that's an adoption problem that will be solved with scale (and I hope it is), but right now, I feel like my luxury Bently sedan got totaled and I'm driving a 20 year old Honda Civic with manual transmission. By all means I'm grateful for the tent, but I still miss my Bentley
