Most local boards are for languages and not for countries. India, Nigeria, Philippines and Scandinavia are exceptions. Spanish is spoken in dozens of countries and even if any of them there will be any other popular language it doesn't mean that it is welcomed in Spanish section. Many of languages presented in Local boards sections are spoken in different countries: Arabic, French, German, Russian, etc. If you want to speak Romansh which is one of the official languages in Switzerland along with German, French and Italian, it would be not good to go to any of these three sections, it would be right to open a separate topic for Romansh language or for Switzerland as a country in an Other languages/locations section.
You are not wrong for local board is about language but you are missing the fact that local board was a board to discuss the topic specifically for
that country or if a global topic being discussed on a local language. I think it’s just confusing on country that has similarity on language like the previous USSR that already split on different country and so on since they share same language before.
I said that you are not wrong since at some local board it’s about language but the discussion on most of the local board is more on the local topics and not about the language alone which you are implying on your post.
You are emphasizing some country. But which country? Look at the Spanish board, their Mercadillo section is divided to Mexico, Argentina, España and Centroamerica y Caribe subsections. But other sections are for all the Spanish speaking. Which country is for German? Austria, Belgium, Liechtenstein, Luxemburg or Switzerland?
If we talk about Russian board then there are dozens of official languages in Russia (if you think that it could be related to some country), but if someone will decide to speak Bashkir or Khanty for example, they should open a separate language topic in Other languages/locations. And there are topics about what is happening in Belarus, Kazakhstan, Russia, Ukraine and other countries, not only of Ex-USSR, anyone interested to discuss anything in Russian and who knows Russian enough to speak without online translator is welcomed on a Russian board! From any part of the Earth and further.
So, of course most discussed topics on the language boards are "local", but that "local" is usually not locked in the boundaries of some exact country. Many of these languages are spoken wide enough.
