Posting to a Facebook Page is the same as starting a conversation. If your fans respond with Likes and comments to your post, you should keep the conversation flowing, until the feedback stops. Otherwise, it is the equivalent of suddenly clamming up in the middle of a conversation that you started yourself!
Participating in conversations is the key to retaining fans’ interest. If you ignore the fan activity completely, you are just pushing your engagement away.
