The first day won't be a lurkfest because players will elect a mayor on that day. On Day 2 the town will be probably busy finding out the mayor's alignment.
Ideally one team member usualy stays in the open (revealing his alignment to everyone) while his teammates watch the behavior of others from behind. The primary discussion chat will be in night chat, at least for the first few nights. When most of the roles become known, players will seek possible alliances in order to survive until the endgame and the lurkers will come out of shadows in order not to be lynched or killed.
I also wanted to include The Mastermind in the first game so that all 5 factions would have a common foe to seach for. Without that common foe the town will fall into chaos unless someone takes the role of "town leader", which is the reason I have included an elected Mayor in the game.
