color:#1F497D'>I’m not trying to hide reality (any more than all
statistics do). I think that it’s reasonable to look at the
activity in the project as an aggregate over multiple release cycles. I also
think that it’s reasonable to treat the ramping phase differently to the
one that it’s currently in, with the community more stable in size and
activity. These two things point to analysis over the past year, since
OpenStack is a little over a year old, and the release cycle is 6 months long.<o:p></o:p></span></p>

able to help you with metrics that position openstack more solidly in the open
source community and help with metrics that mean something to enterprises whom
are trying to make decisions 'twixt openstack and other emergent open source
offerings.<br>
<br>
Ewan, statistics should never hide reality (they already do that by
accident)... and averages are already vague enough by definition. The
real history of the project as a whole and each project individually over time
is as important, at least, as the running averages over any x period of time.<br>
<br>
I've been working on evaluating open source projects in terms of risk and
potential and obfuscated metrics won't help people understand the emergent
energy of projects nor the real participatory velocity of projects.<br>
<br>
Mr. Heck: Oddly timely based on our text conversations, ya think?

year x-axis. This is a reasonable baseline for historical stats, and has the
particular advantage in this case that it trims off the start-up phase of the
project, so the average should go way up.<br>
