Has anybody successfully created a software collective? I think my ideal world would be building applications in Ruby with other late-career folks who are low drama, interested in making money, love talking to customers, and don’t get distracted by shiny new tech that becomes stupid tech debt a few months later. Cultured Code comes to mind, though I don’t know if they’re a collective.
