Hmm, that actually sounds like a great idea. Does it actually need to be reachable from the outside, if you don't want to host any of your own communities on it? Or will it be enough for the instance to just pool data? Apart from no-one being able to contact you via DM, that is.
I'll look into it, having my own home instance actually sounds pretty easy and it may work.
Actually - wouldn't it even be possible to build a browser extension for that? One that just simulates ActivityPub calls, and you just browse on someone else's instance without logging in while still allowing you to comment or vote on your behalf?
EDIT: I've posted some more thoughs about it to another comment, which I assumed was a reply to this one. The more I think about it, the more I really like the idea of a self-hosted front-end for Fediverse apps that doesn't host communities, but only user interactions and allows you to interact with other apps and instances.
I think a cell phone is more than enough for one user, probably 100 users would still be fine. With a store and forward proxy even the momentary disconnections would cause missed messages nor notification
Most important is, a content discovery and sorting now lives on your device
An extension would be cool! I'm currently trying to do something similar, in some sense; I've patched my instance to filter out DB results from public queries so that only my posts and comments are visible (unless I am logged in).
I believe it might be possible, but I'm not sure. It seems that the protocol itself is mostly geared for synchronizing data and distributing updates. From my limited understanding, servers follow users or communities on other servers, which inform those servers that updates should be sent to the requesting inbox. These updates are then used to build up a local copy of the remote page. In the case of a remote community, users interact with their local copy and notify the remote community of those changes.
For example, I am viewing a local copy of this post that I received from lemmy.ml, and my reply to your comment will be stored locally. My server will notify lemmy.ml of this comment (including its contents), and lemmy.ml will notify my inbox if anyone interacts with it (because I am a follower).
It seems that at least some of this syncing might not be necessary... a lightweight frontend could rely on the API of each site it connects with to build up the activities it sends. However, this would probably cause some unnecessary traffic, as such a follower would both receive updates and query the API. Also it would probably break some things, such as
ap_id
(see the multicolored fedilink icon, which points the original copy of the content on my instance).
