I am commenting on the news section of this site which is written by a comparatively small number of writers. I don't see how the number of posts I have or have not made invalidates my comments. If I had written to a newspaper I would not expect the lack of previous letters to that paper to invalidate my views. My comment is no less valid whether I had made no previous comments or hundreds.
As for your response that everyone in the US knows T Mobile US as T Mobile, that is exactly my point. Everyone in the UK knows T Mobile UK as T Mobile so the heading is misleading to us here (and in other places around the world I would guess). I would suggest you look no farther than Windows Phone Thoughts where the heading to a similar article is "Apple Buys T-Mobile US".
All of this is a small point in the general sphere of things, but maybe you could expand the number of writers from elsewhere in the globe. Pocket PC Thoughts used to have a number of contributors writing the lead articles who were geographically spread.
