"Will the newsgroups be propagated to Usenet at large? Will the
newsgroups be accessible through Google Groups?
These two questions are connected; propagation has both upsides and
downsides. The downsides are that propagation means that we can't really
do post deletions, and a failure to control spam may affect developer
participation. It's been decided, at least initially, to limit
propagation to only news.mozilla.org (at Giganews) and Google Groups. We
have agreements in place with both services to not propagate messages
any further. Based on feedback from the community, this may change at
some point in the future, but deciding to allow propagation is an
irreversible decision so we're starting out the "safe" way.
