My take on the content vs lack thereof (by other standards), having played a good amount of both.
With higher content, it's more like live mafia. Yes, the town can't think as well and can't go back and look at all the posts in five minutes, but the tradeoff is that the scum also aren't spending twenty minutes on each post. It's a type of game based on reactions, tone, and connections. Voting changes play a bigger role and are more important, because you don't just make a vote and sit on it obstinately all day because there's not much reason to change it. Votes fly around more, you have more time to figure people out and get a good read from interacting and seeing how they respond. For example, on an activity level 1 game on CFC typically, people make 1-3 posts per day. These are not actually usually deep analysis posts. There's hardly anything to work with. So, in a faster paced game, you may have too much to be able to read, but you can, say, go back and read everyone's posts before EoD. You get much more of a sense of what people really feel. Scum is much more likely to make a tactical error or slip under that set of conditions.
Like (I think) Zack said, the main problem with this game is that you had the five or so players that were maintaining that higher level of activity, and everyone else was just sliding happily beneath the radar. And it doesn't really help the system when it's in neither of the modes, fully. It helps scum point fingers at the people who have made many posts, and some are slightly scummy when looked at from one angle, more so than the inactive people who have just made bland unhelpful posts. There are definitely people in between, but I think you get the point.
