<…> The local boards are not segregated on the basis of the languages but on the basis of the country. The local boards are meant for the discussion of the local nationals on local issues and/or advertisements of the local projects/services <...>
I beg to differ. The Spanish local board for example is covered on a language basis, being common to those members who wish to express themselves in Spanish, be they from Spain, Argentina, Bolivia, Chile, Colombia, Costa Rica, Cuba, Ecuador, El Salvador, Equatorial Guinea Guatemala, Honduras, México, Nicaragua, Panama, Paraguay, Peru, Puerto Rico, Dominican Republic, Uruguay, Venezuela (but not limited to these). In practice, we seems to have a rather small representation of some of these countries, but it’s certainly not delimited to Spain.
What’s more, other official languages used in Spain such as Basque and Catalan are managed as separate threads on the "other languages" board.
There may be a certain local scope of the topics treated by the underlying countries on the board, but in general terms, the common denominator is to facilitate people expressing themselves in a particular language with ease, and topics can and will often be similar to those that are found on the general English boards.
