Today I deactivated all Beta features. First: the talk-pages are only in English. I don't know whether I could only post feedback in English or in other languages and I know, many people don't give feedback at all because of this. (And the feature page for VE is even worse than the other ones) Second: I will not test any software from the WMF, until the Feoundation keeps the superprotect right, which is a thread to all communities.
Topic on VisualEditor/Feedback
Feedback is welcome in any language, there are usually people willing to translate (and google helps a lot). Practically, the language du jour (ha, see what I did there ?) is English however. There is simply not enough capacity to translate everything into all languages and process the information that way.
Regarding superprotect. Well, I blame the WMF for getting us to a point where it's usage was required, i blame the community for pushing WMF into exercising it...
