- In any language supported by google and altavista there is
a substantial pool of wikimedians to supply important comments on the auto-translation.
They would end up having to re-translate everything. Auto-translations are appalling and there is far too much risk of misunderstanding.
- A bilingual discussion not only ''enfranchaises" more wikimedian,
it also allow you to look at the "sources", since many of the comments that would be in English in your proposal would be written in another language and have to be translated anyway.
In my proposal, everything is done in English (or, possibly, another common language - if it turns out more people speak French, say, then everything can be done in French, but I think English is likely to have the most people able to take part), there is no translation. That's why members would need to speak reasonable English. If things need to be translated it slows everything down enormously.
