I am an outsider to this community, but I have always watched this project.
In my opinion, plone is
- a great project
- a great product
- a great community
And it has great leadership also.
I think community building is much more than creating a big project.
May be creating a community with lots of buzz is possible, but making it active always
is not easy. And code base is not the only thing required for a successful project.
Plone is a great success compared to many other big projects.
