Community
• Habari is a meritocracy
– No dictator (benevolent or otherwise)
– No ivory tower
• Everyone has a voice
• Contributions speak louder than words
(but sometimes words are contributions)

The Community Decides
• What goes into the new release?
• What constitutes core functionality?
• … what logo do we use for Habari?
(This one has been going on for quite a while!)
