In this thread: Lies open source developers tell themselves.
It's a sad joke Rubyconf attendees yearly confuse @bryanl and @daksis with each other, but it's happened at every Rubyconf i've been too (which is granted 3 but it's there).
Open Source is a community, and communities are about who you know, and how you interact with them. Open Source communities do nothing to fix or address the structural or cultural elements of racism.
Success in open source is like success in anything else. It's about building something that other people care about, and promoting yourself and your work to others (or having someone else promote it for you). That last component is entirely socio-cultural. There is no meritocratic component to it.
It's again worth noting that the modern etymology of the term 'meritocracy' was satire against the concept we identify it with: http://en.wikipedia.org/wiki/Meritocracy#Etymology
Being good at what you do and working hard is necessary but not sufficient to being recognized and successful.
