blog.mention.com"Now"? This is the first time Mentions has had geolocation, so the US has probably been in the minority for some time. It's not exactly shocking, since Twitter claims to have nearly as many daily active users as there are people in America (270 million vs 300 million).
Good point, the "now" implies a switch that may have happened actually some time ago.
