Why devs only read US forums?

I find it disappointing that devs (GC usually) read/write almost only on US forums. Sometimes there are good topics with interesting ideas on EU forums which don't make into US forums. It's kinda sad that suggestions from EU subscribers are forgotten. A reply from time to time from GC or someone else who is resopnsible for game changes wouldn't hurt. Lack of blue posts from devs shows that this forum is probably rarely/never read and it's community has no chances to push/suggest any changes made into game.
