Check and check.

Not sure how to verify these.

Based on the number of submitted Jira issues, the number of people
submitting them, the number of people submitting patches, the number of
people offering code reviews and testing, the increasing traffic on the
lists (we could do better here though), and the traffic on IRC (we
average > 50 people during peak hours)... Check.

According to the status page there are 8 committers, representing (I
think ) 6 different organizations (or themselves). Some are more active
than others though, so I'm not sure how you'd score this.

Two folks were just recently added.

We've struggled with when, where and how to use this, but I think we are
basically OK here.

A prime example I think:

A roadmap was discussed[0] for 0.3.0, and the fix-for-version metadata
in Jira was used to track the progress. Votes were held for release
candidates[1] and for the final[2]. There was also discussion regarding
post-release support of 0.3.0.[3]

IMO, we've been even better about this for 0.4.0[4] so far.

Not sure here. Could you explain this one?

Obvious not. :)

We use quite a bit of ASF software (several of the commons libraries for
example), but the most prominent example is probably Thrift. There is
some overlap between project participants, and countless Thrift issues
have been filed by members of the Cassandra community (often accompanied
by patches).

All good here too.
