@Evanatt The instances are linked together ('federated'), so you can follow or be followed by anyone on any of them to see posts.
The 'local' timeline just shows posts from people on this instance.
Some instances like here have sort of a specialized theme, so the 'local' part helps limit to just that community.
You don't need an account elsewhere, but you can and it would have its own 'local' line for their theme if any.
Or just follow people there from your account here. personal preference
