Why would I want to browse Lemmy “Local” instead of subscribed? It seems that “Local” can serve up just about anything, including things that have nothing to do with the types of communities that I have subscribed to. If I understand correctly, “Local” shows any post to any community on Lemmy.world, which could be just about anything. So, maybe I am missing the point because I don’t really see why anyone would want that.
Local is showing you all of the content submitted onto the “local” instance, which is the instance your account resides on. I browse locally on my Mastodon account to see what other members of the instance are up to. Still on Mastodon, the home feed is going to be people that you have followed (subscribed).
Basically, I use Local if i’m feeling like browsing just the instance and to connect with people only on the instance. I use Subscribed if i feel like browsing just the content i’ve subscribed to. I’ll use the federated timeline (on /kbin this would be “All” which i imagine is the same on Lemmy? not sure) if i want to cast out the widest net possible. With local and federated timelines, i can find more people to follow or more groups to subscribe to.
So, Subscribed shows only your subcriptions, Local shows only your instance, and All will show content from around the fediverse.
i hope this makes sense
