Open Stack

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.

Ewan.

Stefano, please drop me a line, I may be 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.

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.

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.

Mr. Heck:  Oddly timely based on our text conversations, ya think?  ;)
