> it would be nice to see a bit of statistics like number of releases in incubator, growth
in incubator…

Mailing lists:
The dev mailing list has 123 legit addresses on it and is quite active
for discussion, votes, feature ideas, etc..  We’ve just recently
created a user list as requested by non-developer users which is now
at 38.  We have 30 people who really like to get a ton of emails on
our commits list.

We have produced three releases in the past 6 months with two
different release managers (RM).  Our project adheres rather strictly
to the letter and spirit of the licensing and legal guidance ensuring
that all source and runtime dependencies are properly accounted for in
the source release license and notice and ensuring that every binary
artifact produced also includes detailed and precise accounting in its
local license and notice.  We are now closing in on our fourth release
and I suspect we’ll level off around a monthly release cadence.  We've
put together detailed guidance for how to properly handle the
licensing that augments existing guidance and policy and we've also
created release guides to help ensure we can effectively RM and have
community members participate in the vote:

Commit Activity:
29 different people have committed to the codebase over the last 6
months with 14 different people committing in the past two months.
We’ve received over 67 PRs through Github including new features,
improvements to existing features, or bug fixes.

PPMC Growth:
We have added three new PPMC members as of the time of writing this
and we hope to announce our fourth new PPMC member within days.  We
see contribution in various forms from a significant number of folks.
And there are consistent contributions coming from a couple specific
people in the form of email activity, vote contributions, code
commits, and code review feedback that suggest our pipeline is strong.

Committer independence:
The graduation resolution proposal we put forward includes folks from
several different independent organizations including Requitest,
Twitter, iJet, US Gov, Onyx Consulting, and Onyara.

Should it be necessary we’re honored that some of our mentors are
happy to stay onboard.  While I think we’ve effectively demonstrated
awareness of and commitment to the Apache Way we recognize the value
of their experience.  And thank you to Benson and Sergio for already
