Your examples all come from the Discussion area. Are there examples in the Sequences or Promoted posts that you feel still suffer from this? Have you run in to issues with "main" posts where the authors reaction is anything other than "oh, thanks, let me fix that"?

I don't think policing the Discussion area is a worthwhile community goal.

I'll go ahead and just quote my original response to you:

People in the US use imperial measures as their native units. I doubt anyone on this site uses arshins and sazhens as their primary day-to-day measure of objects. Asking someone in the casual discussion area to translate out of their native units, for your convenience, when probably half of this site uses those units, is selfish.

If half the site were dominated by pre-revolution Russians I would (a) be very confused and (b) once I accepted that this wasn't a hoax, I'd use Google to learn the local vernacular rather than expecting them to cater to me.
