Sorry to intercept 'late' across multiple email replies in telegraphic way ()...
Yes I would be interested to experiment with test instance in incubator of HBS Wikivoyage
or Wikivodič (local name).
@Gerard: I do not get the can of worms metaphore...
As for public, it is cca 20+ milion people that can understand HBS languages.
Fragmantation into small communities over rigid neo-national language standards led to
issues.
This could be small experiment in opposite direction, at no risk.
@Amir: switching script is an issue indeed and I think your idea of separate entities
would be fairly easy to accept by most people from the region as Cyrilic is only close to
same use as Latin script in Serbia.
As for if readers care I would agree many do not, while those that do a fewer and would
care least with HBS.
Wikivoyage is likely less demanding and complex language (for sure less than Wikipedia and
Wiktionary) to do this in acceptable way.
