When visiting the United States, my coworkers and I here frequently come across people who confuse Taiwan with Thailand. Sadly, Americans' knowledge of world geography can be very "USA-centric". I even noticed some of my facebook acquaintances joining a group called "Taiwan is not Thailand."
I couldn't believe it when today I discovered the U.S. post office had committed the same error. Let's all do a better job studying world geography, shall we? (I know there are other areas I'm still fuzzy about).
