I wonder if he's basing this on the main discussion lists. There
actually don't seem to be that many people from Japan and China
posting here on IETF-discuss, despite considerable activity from
those corners of the globe on individual working group mailing lists.
Perhaps they prefer to do real work.
For me that am from Africa, I do prefer to join the WGs in IETF, but
it seems that most meeting of IETF don't come to Asia or Africa nor
provide there a conference room with the live meetings ( IETF needs to
work with Internet Society Chapters in thoes places). I think it is a
challenge to IETF's Works/I-Ds to consider real
inputs/suggestions/applications of Asia and Africa communities to the
IETF. Under the IETF role it is very easy of WG chairs to ignore
minority participants of large communities.
