Subject Re: Tez graduation [Was: Request for mentor assessment]
Date Tue, 24 Jun 2014 06:39:46 GMT
If I am not mistaken, no one really doubt the possible value of Tez
(incubating) for other open- and close-source projects. I don't think it
is an intention of the IPMC or a wider incubator community to pass the
judgement on the technical viability of a project.

What is discussed, on the other hand, is how successful said PPMC in achieving
the goal of community building and diversification. The link to the project
XML was very helpful in understanding the amount of the people involved
into the day-to-day activities. And it's great! However, the question that
remains unanswered so far - unless I've missed the answer - about the spread
of the PPMC and committers?

What is the chances of the project staying alive and vibrant if a commercial
entity will decide to cease its participation in the project?

Regards,
  Cos
