The link didn't work from my part of the world so I couldn't read it, but the title is self-explanatory, so I'll make a point which you may have already made. Previously constructed languages like Esperanto use vocabulary sampled from European languages only, which I suspect is why they haven't become popular. A new language would need to take words and grammar from non-European languages also, such as Arabic, Swahili, Chinese, Japanese, and Indonesian, in order to be adopted in any meaningful scale.
