According to Michael Parks, there are two types of people in open source communities, Tool-igans and Product Jocks. Tool-igans are people who are willing to dig deep into technology and build new infrastructure with whatever they can get their hands on. Product Jocks focus more on end-products and use a more broad understanding of technology to find solutions for the masses. Both groups are a vital part of the open source ecosystem and any individual can be a blend of the two groups in different settings.
