Aside from generally accepted "Bad Citizenship" aka littering, drunk driving, peeing in the subway, I think the level of responsibility correlates to the level of relationship.
Someone in my house gets first priority, and if I cannot accommodate their needs (actual needs, not every preference) we will have a hard time living together.
Someone I work closely with, or go to school with, and see every day (such as officemate, class instructor/student, etc.) gets slightly less but still a certain level of change/accomodation in order to keep our relationship going in a constructive way.
Someone I see regularly but not necessarily sharing space - coworker in the same building, neighbor, church or schoolmate, acquaintance I only see at parties - there is no reason to change daily habits, but I might plan ahead if I know I will see them. If I don't know when/where I will see them, no way to plan for anything. The neighbor mentioned on the blog thread, who was running a commercial laundry operation and caused hardship for the sensitive neighbor - that was unfortunate, but unless the business was being illegally operated she had no obligation to change her ways to accomodate the sensitive neighbor. Might have been nice, but expecting the whole world to conform to unusual requirements is unreasonable.
Our responsibility to the general public and the world at large is generally covered by laws and basic rules of etiquette. As long as you are lawful and polite according to accepted standards, (don't clip your nails in public! Don't wear so much scent that people outside your personal space can smell you!) then making up new rules in unnecessary.
