I'm reading now a book on Russian Revolution, where speaking of discomfort inside the Russian Army before Revolution says that soldiers, mostly countrymen, were very displeased because of officers addresing to them with "ты", a treatement used to addrees to animals and children, instead of more formal "вы" since, being the officials from noble families and the soldiers from previous serf families, remembered a recently passed and heated state of things.
Putting apart that Pushkin was very happy for being treated as ты instead of as вы from his beloved , what is now the state of things in Russia? Is general the use of вы and ты is strictly limited to address to young people, friends and family? For example, should be correct to address to everybody in this forum with "ты"?
