Actually in the article I proposed only to think to people that don't know English but want to be part of the community. I think accessibility increase if more people can contribute.
Yeah, and what people are telling you -- which you seem not to quite want to understand? -- is that the best way for these people to become part of the community is for them to learn English.
I'm totally aware that the only way to become part of the community is to learn English, because it's exactly what I've done and I've written in the article, but I wrote also that this is not inclusive and the community can change this status quo.
Conversely, in the linguistically fragmented scenario, you're SOL, as it's pretty unreasonable to learn N different languages.
