Some quick thoughts from my perspective:
JM: good job making the winning pick there.
Innos: holy ****, there was plenty of evidence that michael was inno and you STILL voted him out. WTF did he need to do to prove it?
Ctown: inno MVP with that write up at end of day 3. Nailed SCNCY, azhuth AND Fitzy
Fitzy: crushed it on determining which innos were special (Vikes based on singling out the top group from day 1, GBlade as the only one who would have the information to vote the way he did)
Also Fitzy: in the game thread itself he only ever tried to direct innos away from mafia. If anyone had ever gone back through his posts they would have pieced together a quality list of innos.
SCNCY: things were going well for mafia, then he tried to lead that charge on Ctown. Sometimes things just don't work out...
My broad takeaways if I wanted to help improve innos trying to find mafia: those lists of players who everyone thinks is mafia are so useful. Too often we get into "vote x player" mode and everyone jumps on without talking it through.
Second, look at the big picture. Fitzy convinced folks not to vote him out by pointing out a couple good things he did. But if looking at the broader picture the evidence pointed to him being mafia.
Third, and third is similar, don't forget what happened one or two or three days ago. Ctown put out his manifesto and crushed it, and then he died and everyone ignored what he did. That's just one example, but ir happened a few times where folks got distracted by the new shiny person at top of votes.
