That's intriguing. Could you please elaborate on that? Does this mean that Twitter sees no danger in exposing these? Which parts of the infrastructure would be considered secret sauce and not open source? Or does it not matter when the company is as big as Twitter, since the core strength lies in user base, not technical infrastructure? What does Twitter primarily seek to achieve when it open sources its stuff? Talent acquisition or brand image or other benefits of open source such as collaboration?
