You configure your client post your content to one or more relays. You can use relays that you setup for just yourself, paid relays, and/or free public relays.
When you follow someone, or someone follows you, the follower's client will get a list of relays the person they want to follow is posting to. The follower can connect to any of those relays and get any new content.
On many relays it's possible to get a firehose feed of everything posted to that relay. On free public relays this firehose feed may contain lots of spam accounts.
