a small difference, but important to how people use the site
Boosting is super important in all contexts in the Fediverse.
When am instance subscribes to a content source - be that a user actor or a group actor - on behalf of a user, it only requests future content. Back catalogues are not fetched by default. Boosting re-publishes the content, so that it is received by new followers.
With a group actor, the boost triggers the actor to reboot the content itself, sending it out to new subscribers to the group, and filling in that back catalogue.
if old content isnt fetched for a newly subscribed instance to see, how are users going to boost that content in the first place?
Users who can see the content need to boost it?
Users who use the website that the community is hosted on have access to the full library of it. They need to boost stuff. And people who subscribe from remote sites need to boost older content that they’ve seen.
but relevant users cant see it, its never fetched for them to see it. Sure users on the home instance can see it, but they’re on the home instance, it’s already fetched for them. Ive run into this problem on here, where there is a lot of content on other instances that isnt visible from kbin. I have the option of visiting the home instance to see it, but it takes me completely off of kbin, I cant boost it from that page.
