Del Harvey: The strangeness of scale at Twitter

“If I start by assuming the worst and work backwards, I can make sure that the protections we build work for both expected and unexpected use cases.”

“Given that I spend my days and nights imagining the worst that could happen, it wouldn’t be surprising if my worldview was gloomy. It’s not. The vast majority of interactions I see — and I see a lot, believe me — are positive, people reaching out to help or to connect or share information with each other. It’s just that for those of us dealing with scale, for those of us tasked with keeping people safe, we have to assume the worst will happen, because for us, a one-in-a-million chance is pretty good odds.”
