So I head on over to the Mastodon website, and I'm shown a list of 40 servers that I can choose to create an account on. Most them are very niche - either dedicated to a specific country or city, a cause, or some sort of tech scene. There's no obvious way to find out what the experience is like on any of these servers, just a button to "apply for an account". If I click on that, some of them will show me a selection of posts, although it's unclear if those posts come from that specific server or from elsewhere.

How am I supposed to decide where to create my account?
