Principles. That the whole internet and all of the freedom and diversity it can harbour was being monopolised by big giant corporations that had no interest in embracing an open web. Instead, they were convincing the world, especially those growing up in that/this era that the internet had to be constrained to the few walled gardens of big platforms.

These principles were as obvious and relevant then as they are now. Unfortunately convenience is a helluva drug. And, in the "Google" era of the internet (~2005-2020 ?), there was a certain naive optimism about big-tech and the internet, which no doubt lulled us in by its being "free".

In reality, we all really thought that good and useful world-changing stuff was just going to be made for us for free. That the internet was going to inexorably make the world a better place. It was dumb and naive IMO and marks very well the failings of the Millennial generation (to which I belong FWIW). Unfortunately, it's a lesson we had to learn the hardway. There were probably only a handful of people in the world that understood what the new industry was actually doing and was actually about and that had the philosophical will and ability to think it through and communicate to the masses what the choices we were actually making.

We could turn to good ol’ PGP

Possible doesn't mean easily doable, unfortunately. Technically speaking, I don't know how hard it would be for the fediverse. I get the sense that overall it's been a mismanaged aspect of the ecosystem for a long time.

It touches on a broader issue of to what extent the software ecosystem enables users to exist on the fediverse at large as a single user or through a single interface. At the moment, it's basically not really a thing. Arguably, if the fediverse wants to make any claim to being an actual "federated universe" rather than just separate FOSS decentralised platforms (there is a big difference IMO) ... then it should definitely be a thing.

In relation to DMs, then, in a "true fediverse" the answer would be simply something like integrating matrix into your interface such that you and I could easily start a space on matrix and start chatting there if we wanted to.

I've come to the conclusion that for this to happen it needs to happen at the UI/client/app level. In fact, I wouldn't be surprised if that happens in not too long a time. An app that understand and works well with all of the major platforms and gives you a single and well designed interface for working with all of them from a single space. This way the platform developers can focus on their specific funcionality and backend while the app/client developers can focus on the UI and the challenge of bringing things together. I see it as similar to the way we all have email apps that easily bring together multiple email clients.

Up and down votes are federated with your username, along with posts and comments (obviously).

Clicking on links, favourites, email address (if you put one in when signing up), password and IP address are all only on your local instance.

Basically, unless another server needs to know about it for federation to work, it's going to be local to the instance you're using.

I don't think the fediverse necessarily needs to be replaced. We still have, afterall, Twitter going hard and strong after nearly 20 years! THe fediverse may very well go strong for many years to come, and that'd be a good thing ... it's nice!!

In an ideal world ... what would replace this? IMO, technology that basically gives every person a secure home on the internet in the same way that (most of us) can have a secure home in real life. Control, ownership and privacy over what you consume and publish and how. That technology would need to involve a number of things on a number of levels, but I'd bet it's quite viable today, it just needs buy-in and people to have the time and resources to build it.

How many of you are there?
