While OSS and mainly FLOSS provide great solutions the implementation is what sells the project. From snazzy installers to finely worded documentation many aspects of a project are constantly a splinter in the implementors thumb. As an implementor I work to smooth ruffled feathers and explain difficult topics. Asking what "we" could do to remedy this is so out dated. I smile and explain, smile and apologize, smile and sell my services. What "I" need to do is get individual people involved. People with great ideas or knowledge that normally don't involve themselves with software. The social capital is there, I do the favors and the pro-bono work. How to apply this capital to interest my peers into contributing to the community?
Giving is not just money, its time and knowledge and sharing.
