if you want someone to reply to you, try to talk about THEIR muse in your response to them a bit. write a thought about their character, make their muse seem interesting in what you say. it show that you’re actually interested in the other persons character and paying attention to them and their mannerism, it makes them WANT to reply to you. it’s easy to talk about your character the entire time, but that can be discouraging for the other writer.
