Following up on this, here's a quick graph I put together when
preparing for this month's board report:

The graph shows how podlings have moved from one (subjective)
categorization to another (or to graduation/retirement) between their
two scheduled reports in the February-July time frame (I'm only
counting projects that were already past their first three months at
the Incubator). The edge width is proportional to the number of
podlings that made that particular "state change". The Graphviz source
of the graph is included at the end of this message.

The overall picture looks pretty good. We have strong movement towards
graduation, and so far no regressions from the "ready to graduate"
state back to low activity or diversity.

Here's the list of projects that stayed at the same category from one
report to the next:

  IP clearance:      Amber
  No release:        Any23, Bloodhound, Cordova, JSPWiki
  Low activity:      Ambari, AWF, EasyAnt, Kitty, Nuvem, PhotArk, Kato
  Low diversity:     Airavata, Bigtop, Chukwa, Tashi
  Ready to graduate: Flume, Lucene.NET, NPanday

The IP clearance issue in Amber seems to be finally resolved ( LEGAL-134).

The release issues are being resolved, as Any23 has just passed a
release vote and I've seen good progress towards an Apache release in
both Cordova and JSPWiki. I don't know the release status in

The low activity projects remain a problem though there are a few
projects who've managed to escape that trap. For the rest we need to
find solutions. Kato was already retired, and AWF and Kitty getting
there. EasyAnt might go the subproject route, and PhotArk has been
showing increased activity lately. I don't know what's going on in
Ambari or Nuvem.

The low diversity "state" is a bit vague catchall category for
projects that don't yet feel ready to graduate. I'm not too concerned
if some projects take a bit longer there as long as they don't regress
to low activity. Once a project has hit the "low diversity" category,
chances are quite high that it'll end up graduating.

The podlings that were "ready to graduate" for more than three months
are a bit mixed story. Flume already graduated and Lucene.NET is just
about to, but NPanday looks to be in trouble as activity there seems
to have plummeted since May for some reason.
