no, I disagree.
why do you need to propagate British colonialism anyway :\ ? it's bad enough having to deal with that garbled English speech-no offense-, now they should also formalize it in writing? =_=
also, the Japanese were defeated/colonized by the West, thus they use Romaji-note: Romanji is a common misspelling-, not to mention due to their extreme isolation for so long their language is too unique to stand on it's own internationally.
as Asians, we should use Asian script/s, it's a matter of pride and culture preservation. the same goes for all peoples.
I mean to say unless under necessity, a language should be preserved-by it's speakers-at all costs. it's not simply a form of communication, it shapes understanding as well as connects a people to their past thus preserving the basis of their identity.
the idea that writing in garbled English then asking someone to translate it to standard English is frankly ridiculous, why not write in your mother tongue then ask the translator to do his/her job? why erode your own language even further?
one who speaks English and doesn't know how to write should learn to write as laziness is no excuse, otherwise there are many who are proficient in both languages all around, the person could ask them for help as they learn to write, problem solved.
see brother, I don't mean to be harsh, your idea is worth looking into, but it's not so practical I think. I apologize if I've heart your feelings.
