Looks like it’s for feeds and the fediverse
Since I tried searching for the URL and didn’t find it, but happened to see this thread, you can see more info and sign up here:
The blog states it’s still missing a lot of stuff and it’s a work in progress. If they have to implement every type of fediverse post like peertube, Pixelfed. Loops, etc it’s gonna take some effort.
I assume that’s the goal after reading the post but of course we will see.
