I am genuinely baffled (but I don't think I'm right and you're wrong... I trust HN people to be smart and capable). Can you please explain to me how using tabs vs spaces would encourage people to indent their code differently? I mean, if I have an "if" statement, then I indent my code -- but why would people indent their code for reasons other than what the flow of the code suggests? And if these hypothetical "indenting just because I can and not because I should" people exist, how would their inconsiderate behavior be any different whether they are using tabs or spaces?
