Steve and Kevin have both touched on what I was hoping for when I sent
the initial note.  That is to try to make a place for developing heat
templates, and a path to get there for those who might contribute.

Ryan asked a key question that was definitely not clear from what I was asking:

I was thinking of this from the perspective of all the people who have
access to OpenStack clouds now (whether private self-hosted clouds or
the dozens of public OpenStack clouds people can use today).  The App
Catalog is meant to be a showcase for things that you can do with that
cloud; packing it full of useful Heat templates would be excellent.  I
am thinking standalone templates, basically like the great set of
templates available on Rackspace cloud [1] but ones tailored for ALL
OpenStack clouds.

I do not believe just creating a repo will magically result in people
adding templates there (with expert guidance from unspecified core
reviewers).  But it feels to me like we are missing a place and
community for sharing the templates that are being developed (or the
ideas that could be turned into templates).  Like Kevin pointed out
for the work J^2 did for the Chef templates, there's no obvious place
to go check first to see if someone else has created and shared a
template before you start working on one.  Ideally the app-catalog
becomes that place, but I'm trying to figure out how to engage the
Heat community in making that a reality.  If making a new repo is not
the answer (and I agree with most of the points in this thread -
that's not the way forward), let's see what else we can do.

Can we agree the world of people using OpenStack would benefit from
having easy access to Heat templates that stand up applications for
users?  Given that, what would be the best way to start collecting
what already exists, and start encouraging newcomers to contribute
there?
