So, if I have a piece of local aviation info which is mainly of interest to a limited native audience (and ex-pats from area), nobody else are gonna miss out on much if I use our local language.
On the other hand, if posted in English it may educate the general public – if they'll bother to read something that is of limited or no value for them.
Don't see why this is still debated, as the moderator has already clarified the issue. But please continue the creativity – it sure is great fun to read all those language samples!
