RVM Saves the Day for Octopress

Octopress is a lean blogging engine that happens to power RayHightower.com. Earlier today, after a quick update to the blog, I encountered the following:

Successful Companies Are Built Around Communities

Seth Godin is on a mission. Technology enables us to form communities that stretch beyond traditional boundaries like age and social status. Godin is convinced that revolutions within and between communities will yield huge opportunities for those who have the courage to take action. Don’t waste the revolution!

PechaKucha: Developer Education at TableXI
