I think some clear issues need to be set out here. First, there is no such thing as an economy without a country, so I do not understand this point about "Economies of the World".
Not true, but the reverse is true. There is no such thing as a Country without an economy but it is possible to talk about economies that are not countries. For example I could talk about the economy of California but California is not a country. My point of changing the name for Country to Economy was to leave it open for you to derive your own rules as to what Economic blocks you will use. It's not for me to dictate that the Economics workgroup should use as it's division. If you decide to use countries or states then that's up to you.
Secondly, countries as such are not the sole province of the Geography discipline.
I am not implying that countries are the sole province of Geography. What I am saying is that the catalog will get too big if we include every possible metric and demographic. We should have several catalogs that deal with a group of related metrics. So one catalog would discuss the geography of each country; another catalog would discuss the economy of each country; another discusses the politics of each country; etc. We would use effectively the same list for column 1 of each catalog but the data in columns 2, 3 and 4 would be changed for each.
Thirdly, there appear to be no Geography Editors appointed, so who will approve any articles?
Lack of an editor should not stop us writing. Editors will join eventually. When they do, they will hopefully have something to approve (or, and I hope not, disapprove) rather than a set of blank pages and big to do list.
