In my opinion, there are two big things holding Lemmy back right now:
-
Lemmy needs DIDs.
No, not dissociative identity disorder, Decentralized Identities.
The problem is that signing up on one instance locks you to that instance. If the instance goes down, so does all of your data, history, settings, etc. Sure, you can create multiple accounts, but then it's up to you to create secure, unique passwords for each and manage syncing between them. Nobody will do this for more than two instances.
Without this, people will be less willing to sign up for instances that they perceive "might not make it", and flock for the biggest ones, thus removing the benefits of federation.
This is especially bad for moderators. Currently, external communities that exist locally on defederated instances cannot be moderated by the home-instance accounts. This isn't a problem of moderation tooling, but it can be (mostly*) solved by having a single identity that can be used on any instance.
*Banning the account could create the same issue.
-
Communities need to federate too.
Just as instances can share their posts in one page, communities should be able to federate with other, similar communities. This would help to solve the problem of fragmentation and better unify the instances.
Obviously there are plenty of bugs and QoL features that could dramatically improve the usage of Lemmy, but these two things are critical to unification across decentralized services.
What do you think?
EDIT: There's been a lot (much more than I expected) of good discussion here, so thank you all for providing your opinions.
It was pointed out that there are github issues #1 and #2 addressing these points already, so I wanted to put that in the main post.
1- You mean something along the lines of Hubzilla's nomadic identities? or how?
2- This is a good Idea. But I'm not sure how posible it is as of now
I'm not familiar with Hubzilla, but it sounds like one possible solution!
I've never used Hubzilla or its cousin project friendica. But I know nomadic identity is a unique feature of the former.
For what I've read, it allows you to keep your friends and content that are also hosted on hubzilla, but any person from another platform you follow would be lost (you'll have to re-follow) if you move instances through nomadic identity.
Putting a hypothetical lemmy nomadic identity as an example, If you move from a lemmy intance to another using clones, any community you subscribe to that's based on lemmy will remain, but any kbin magazine you subscribe to would have to be re-subscribed
Wow me neither, looks promising!
NFTs
Eh?
It's a joke. You could have your account tied to an NFT. Then transfer it to another instance if you want.
