Георгий Ильин (2017-09-11 20:17:31+00:00): My name is Георгий, not Григорий )))) Moreover, I see no provocation from Poliakoff Mykhailo, just emotions. Anyway, guys, please don't get personal (both yaugenka and Mykhailo). Let's keep this discussion calm and constructive.
About your arguments:
1) This doesn't change the fact that the toponymic signs are displayed in Belarusian and putting that info in Russian as a main language only creates confusion. Moreover, guys! Please! Don't think only of Russian-speaking Belarusian people! Think about people like Ambush and me who use their phones in Russian, and arriving on-spot they can see only the toponymic names in Russian on their phones, but can't see the name that appears in front of themselves! I've got family and friends coming to see me from Russia and they get confused each time because of the name differences, so they switch to Yandex or to Google to be sure!
I am not sure if I understood correctly what you mean by "Local public service vehicle tickets", but anyway, if we keep the Russian name in name:ru, the place will always be found. Moreover, no one talked about changing the administration-related names (as far as I know, those are always in Russian)
2 and 3 and 4 (they are closely related). The local convention was wrong from the very beginning, because it was against OSM's main rules regarding names ("in disputed areas, the name that must appear is the one on the sign".Anyway, the address issue you are highlighting is a good one as we have been discussing between ourselves for a long time on this topic )))) 
A blind following of the initial local convention is exactly what is leading to chaos. I think Jay May made the most fair proposal: street signs bilingual (1st BY, 2nd RU - we should have a look how they do it in Brussels), other toponymic names in Belarusian, and commercial names (I will add "Administrational" if everyone confirms me this info) in Russian.
5. Sorry to say that, but of all the topics you mentioned, this is the less relevant. I am Russian myself and each time I use my OSM-based maps, it freaks me out to see the name I see on my screen is different from the one I see in front of myself. Moreover, we must remember why we are here. OSM is not an ethnographical nor a linguistic project. Its aim is to show the ground reality as accurately as possible, and to make people's lives easier.
I don't see what kind of reading and editing dificulties it may cause. Nowadays, all computers give the possibility to switch from language to language, from alphabet to alphabet. Until now, people were not able to see the Belarusian names at all as not all phones propose this language, and no one is going to switch their phone to Belarusian just to see the toponymic name. Some people even see it as a discrimination of the Belarusian language in favour of Russian. I personally see it as... making life more difficult for Russian-speakers while trying to save Russian language in Belarus! You don't need to try to save anything - Belarus is the only country from the former USSR where the use of Russian has increased, so you will have lots of users like me using OSM apps in Russian and happy to see the original name below the Russian one ))))

I am looking forward for your cooperation. If you see that during editing, someone removed the "name=ru" tag or that someone unnecessarily changes the name=* tag, please highlight is. The aim of our group, I repeat it, is not to "kick out Russian out of Belarus", but to reflect the reality: Russian where there is a Russian sign, Belarusian where there is a Belarusian sign, English where there is an English sign, etc. )))))

Thank you all for your attention! Спасибо всем за внимание )))))
