In Defense of Pace
Understanding how you can control pacing in a game is extremely important to unlocking the best methods of provoking useful reactions from players.
I define pace as how many different reactions there are on a given topic of conversation. For example, if a certain player is questioned for voting no lynch in a game, the number of different responses from players determines the pace of the game. In a well-paced game, by definition the responses are more diverse and thereby provoke more discussion. The more helpful the discussion is, the more players will seek to contribute, and the more posts you will have in a thread.
A brisk pace is necessary for the enjoyment and the success of any town in any game. Analyzing whether a player is lagging behind the pace allows you to see who is lurking and who is not: if someone is not responding to discussion, he perhaps does not want his thoughts to be seen. Pace keeps players interested; I would much rather read something that generates excitement and responses than boring, passive posting. Pacing allows the game to remain intense and full of twists and turns.
AA and PA
Specific posts have two kinds of pace: Active Affecting posts (AA), and Passive Affecting posts (PA).
If there is a response or reaction caused by a post, the post is actively affecting the game. A question is the simplest way of actively affecting the game: you are providing the opportunity for a player to answer the question, thereby adding another response or reaction. Provoking interesting discussion is another way of actively affecting the game.
If there are no reactions or responses generating by a post, it is passively affecting the game.
Making a Post Actively Affect the Game
Questioning players is the best way to ensure a post will be actively affecting the game. Whereas with any other AA post you are fishing for responses, a question must be replied to, or there are huge consequences for the scum.
Always try to condense posting material if possible. Anyone can be verbose, but taking out unnecessary parts or simplifying your language will make your post much more readable. And of course, the more people who read your posts, the more replies to it there will be.
Another general way of increasing the pace of your posts will generally be to present your posting in a new and original way. This does not necessarily entail a massive playstyle change, but making sure that players will want to reply to your posts is a good skill to have.
