Why do so many articles about the Kernel culture assert Linux has a contributor problem? Whenever Greg K-H does his contributor report, it looks like the largest collaborative software project ever shows no signs of slowing down. Are there reports or complaints from the Kernel maintainers that I've overlooked? Are the main barriers to entry no longer the technical skillset, intimidating problem domain and desire to work on kernels? I honestly don't know. If anything I think that the kernels contributor problem is that it's too attractive compared to chopping wood next door in the userland libraries and core processes. Note: For this post I'm not trying to say anything one way or another about the complaints towards the social environment of the Kernel community, I find this a particularly poor point to use when arguing that message.
