w00t :-)

I think these are sensible principles, but we shouldn't disregard the
Zope community outside Plone. Hence, if Zenoss, Silva, ERP5 and others
are willing to contribute and maintain code, they should not feel
shunted out of the development process.

That's not to say we should succumb to indefinite maintenance of all
components on the odd chance iet may be needed by "someone" (we'll
have a stable Zope 2 branch for that), but I believe we're stronger as
a bigger community with more voices than as a narrow group with only
one goal.

+1 - GitHub is really useful.
