Like many others, I created accounts on a few different instances to try things out. Using apps like Liftoff and Jerboa make it very convenient to switch between accounts, but I’ve noticed that I get different posts showing up when browsing All, even with the same sort settings.
Can someone explain why that would be? I don’t think any of the instances I’m on are defederated, so shouldn’t I see the same posts across different instances?
All timeline is all post from subs/community that you and your instance-mates subscribe. Each instance has different users, and different user follow different communities. Hence All timeline can be different for each instances.
If a user follows something from Mastodon (for example) will that also begin to show up for the rest of their instance’s All timeline?
AFAIK, no. Lemmy only shows posts from group actor a.ka community. And only shows comment from normal user as child of posts.
