A forest is a complex ecosystem of plants, animals microorganisms, non-living material, all balanced delicately by nature. It requires the right geography, the right soil, the right amount of rain and sun, and decades to build a forest.
So is open source. An open source project is a delicate ecosystem of contributors, reviewer, users, supporting organizations, all balanced by a feeling of a community. It requires the right ideas at the right time, the right group of developers, the right technology, an enormous amount of dedication and passion, and years to build a project.
