As a developer, ==you can freely build apps on atproto because open protocols are locked-open APIs==. However, if you just want to introduce another way of showing people posts, or moderating content in the network, we are designing interfaces for you to plug in and do exactly that, accessible through our app. ==If you’re building a new social app, you’ll be able to tap into the social graph and interest graph of atproto users the way you are currently able to bootstrap off of a user’s phone contacts.==

The promise of building an audience on apps built on atproto is that long term, it should become a protocol like email that lets you keep direct connections with people regardless of how the services mediating that relationship change.
