I find that British people are increasingly likely to use Americanisms too and I think it's a natural consequence of today's global communication culture. Personally, I mix Americanisms and Britishisms con gusto, since I come in contact with about 50% of each and English (of any kind) isn't my native language. I tilt towards British English though - it's how I was taught to spell, and I sound distinctively British when I speak. Well, to myself anyway. Interestingly, I was working in an international group a while back, it turned out everyone thought I was Irish, so maybe that's how I really sound? Or do I use Irish-isms? What are they?
