@Temrin e.g. I followed you after you sent your first toot, so by default my feed just shows nothing: https://social.kithop.ca/media/XAHnh1qtpOZpoRE7JsQ
However, if I click your profile picture, it opens a tab with your actual feed as it is on the mastodon.social instance, which shows everything you've made public:
@Temrin There's a special 'Federated timeline' that is 'everything my instance knows about every other instance in a global feed'. I don't use it that much, because on a big server like yours it can be pretty spammy. Think of that kind of like Twitter's 'trending'.
