Responding to conversations that are already happening is often a smarter move for a brand that is still building its audience. When people are already talking about something, there is an existing interest in that topic. Jumping into those discussions with something helpful or thoughtful gets the brand in front of people who are already engaged. Starting conversations from scratch works well too, but it requires a bit more authority and trust before people actually respond. Both approaches work, but responding first tends to be easier for newer brands.
