day 1 for me is just the beginning of sorting and organizing thoughts about some players based on what they have posted, then gradually update that information as days progress. If my past experience has taught me anything, I gotta be pretty careful not to become biased towards someone because I either hard town read them or scum read them on day 1.
Some scums will try to appear town, whereas most towns would naturally appear town. Then there are those in both alilgnment who don't really care about their appearance and generally harder to read. The latter group makes it harder for me to develop a read, most often contribute very little, if they are present in the game at all. IMO, there is no point going for people that are letting themselves to be read (town/scum) on day 1, because you can either strengthen or weaken your stance about someone as days progress. But if you have this group of players that aren't really helping with solve (be it predictions, speculations or whatever), you can't really develop the game. It just becomes a guessing game. So I'd rather vote the latter group of players than the former.
This is my personal preference. Of course if someone is playing scum alignment with their cards facing up on the table (strong scumread), i'd go for it.
