I know - got the above link and had a quick look at Chris' response again
I think the thing that gets some of us going is the lack of clarity between GENEALOGY as in native place or place of origin and in Political Boundaries/POSTAL ADDRESSES
Quoting this from Chris' response - "We could do simple text matching, e.g. "London" to "London", but that breaks down quickly when there is a London, England, and a London, Great Britain, and a London, Ontario, and a London, Ont., etc., etc."
But that is the point you see - there is no place for "London, United Kingdom" or "London Great Britain" in family history; its London, England - and that's all. If you were born in London you were born in England - or in "London, Ontario, Canada" - what's hard about that?
