Lyra isn't designed with any particular context in mind. We aim to allow the full expressive power of language, not imposing any ethos, topic or atmosphere. Lyra is a communication tool, not an opinionated social space.
You don't converse just to exchange news or learn. People converse to tell stories, to laugh, to discuss, to exchange points of view, to convince, to refute, to pass time, to plan, to reminisce... Lyra is like a blank sheet of paper. It doesn't tell you what to talk about. That's up to you.
