Of the people who say anything about it, there seems to be two mutually exclusive camps of people on Lemmy in regards to how it should be structured.
There's those who want it to be a drop-in replacement for whatever platform they migrated from (Reddit, ususally), with everything cultured in one simple, easy-to-browse place where there's enough activity to support diversity, just without the enshittification, even though the centralization they crave is exactly what invites the enshittification...
...and then there's those who specifically want the site to stay fragmented, because that's the whole point of federation, it keeps out all the riff raff, and prevents the platform from losing what makes it so great. But many of them complain about why it isn't growing as fast as they'd like it to, despite the fact that the fragmentation of community is by far the single greatest barrier preventing the mass adoption they yearn for.
Each one seems to want a piece of what the other has.
It's kinda neat when you do, though. For the obvious reason, of course. But I find also that it has the extra feature of showing you all at once just how many accounts you really have.
For most people who use the Internet, I expect it's easily dozens, perhaps over a hundred. It is truly no wonder why people reuse passwords or rely on simple algorithmic tricks to remember passwords, there is literally no way the common person could develop a unique secure password on their own for all of these services and recall all of them. A secure password manager is truly the only reasonable solution.
