Open Source Meme Map (Click to enlarge)
Clearly the map is not exhaustive, but meant to be representative, particularly for the green "example" bubbles. One thing I'd add, that I think is important is that many (most?) Open Source Software (OSS) projects fail---and that's OK.
One of the things I'd like to understand is how this map changes for internal projects built on an open source model. There are a number of companies, like HP, using open source development ideas and tools for internal development teams that are distributed. Clearly some things change. I think the strategic positioning is the same, but the user positioning is clearly different. Likewise, the core competencies are still important. This raises the question of how much of this is specific to open source and how much is Internet-era, distributed development methodology and whether that ought not to be studied in its own right as a necessary, but not sufficient component of the OSS movement.
