I'd like to more depth to the majority of the news site articles, bbc is great for getting the big picture in small portions over a whole range of issues but can sometimes really like the meat I want to chew into. There, at the minute, the best place for more depth is the verious blogs. Nick Robinsons is pretty good for UK domestic politics. I also nip over to telegraph.co.uk
I use US News & World Report - Breaking News, World News, Business News, and America's Best Colleges - USNews.com for my transatlantic slice, if theres a better alternative I'd be happy to hear about it.
