Something I found is that while you can see activity of local communities in your instance like for example a lemmy.world user on lemmy.world. If they go somewhere else like lemmy.world/c/[email protected] that's pretty much all you'll be aware of aside from what someone from lemmy.world pull so it shows up on /c/all
You have to tab open and see lemmy.one to get the picture of the instance as a whole to see what is the activity local to it.
This makes it harder to find new communities and also for new communities to grow. And doesn't help that when you view a community for the first time after someone subscribed for the first time it doesn't pull all the comments, so it looks like there's no activity.
So it would be nice if there was a quick toggle to do a view from your instance and then a view from the instance the content actually originated on.
