 1. **Conversational**. We write how we speak, and that makes us approachable and relatable. 
 2. **Thoughtful**. We want our readers to feel like they belong, so our messages to them should always be cultured and intelligent. That’s why we write with a specific person or group in mind. 
 3. **Reliable**. Twilions are smart, tenacious, accurate and authentic. We know the ins and outs of the products and topics we’re writing about and we speak truthfully about those subjects.
