Note Submitter: forsjudd at gmail dot com ---- The description here refers to "groups of thousands" which is understandable if you already understand what it means, but I think the better phrase might be "groups of 3 digits". It is only occasionally and incidentally that those groups of 3 are actually referring to thousands. And the ensuing discussion about other types of groupings might certainly be clarified by not using the term "thousands".
