It's a big world. I know far more than the average American about world geography/history - as, I suspect, do most Freepers. I still don't know a tenth of it.
Thanks to Web browsers and the eagerness of FReepers to help, we can view an amazingly detailed topical map of anyplace where something is happening, and not just on earth. Our world already includes Mars and the moon will be coming on line soon. Not to mention Hubble views and maps of the entire visible universe all the way out. We know the geography of Kashmir and the wild back country of Pakistan or anywhere OBL is sighted next better than most know the geography of their next county, except for those who actually live in Kashmir or Pakistan.
