Each IETF document mentions the authors place address (I may suggest adding region, as a categorised by IETF), but not sure of history statistics of how many IETF-documents produced by authors in South America, Africa, or Asia, or others. I think it is a good marketing start for IETF to get more Informational-RFCs input from regions by guiding their inputs. Furthermore, if IETF helds a meeting in one region with very low participation, then Why not that IETF encourages people to involve in joining authors of interested documents to that region and interested to IETF as well?
