There is https://piefed.social/topic/chilling:-). It is too early to be recommending PieFed for a mainstream non-technical person to make an account on, but perhaps you could use that as an example to represent what such a feed could look like?

Though I for one am loving PieFed so far:-). I do have to fall back onto Lemmy quite often for tasks such as searching or performing mod duties or previewing how content will look prior to posting, but there are so many things that PieFed can do that Lemmy cannot. Like resolve 50 notifications with one button press, and either enable or disable notifications on a per-item basis (a comment or post or even an entire community, whatever), and block all users from an instance, and it embeds YouTube to show a preview and watch without leaving the site (in fairness, Tesseract likewise can do the latter for Lemmy, and also uniquely adds doing that for Loops videos as well - see it in action here).

For people who like to fine-tune the control of their environment, regardless of whether they use Arch Linux btw, PieFed is really awesome… so long as you know how to fall back onto a Lemmy (Mbin?) when you need it. i.e. for the early adopter mindset it’s a great (almost) daily driver already. And this even without knowing how to code, but for someone wanting to run their own instance it’s even more amazing since it uses Python rather than Rust for the back-end. (There’s also Sublinks that uses Java, but no developments have been announced for a long time due to family issues by the main developer).
