I think that because HubPages is seen all over the world, to comment on one rudely, is well, just sort of rude. Do we think that much of ourselves as being English speaking, that we need to treat those who don't speak English as beneath us?
If I don't understand the question, I tend to ignore.
I also look at the Hubber, and see if they just joined to ask questions, then most likely they are not here to write. Just happened to Google and stumbled upon HubPages in their quest to find an answer.
