Why Twitter’s Dying (And What You Can Learn From It) • 2015 Oct 13 • Umair Haque • Medium

The problem of abuse is the greatest challenge the web faces today. It is greater than censorship, regulation, or (ugh) monetization. It is a problem of staggering magnitude and epic scale, and worse still, it is expensive: it is a problem that can’t be fixed with the cheap, simple fixes beloved by tech: patching up code, pushing out updates.

…

The social web became a nasty, brutish place. And that’s because the companies that make it up simply do not not just take abuse seriously… they don’t really consider it at all.

…

Q&A in technology is considered an issue of code — not conduct. Technology as a culture is so out of touch with reality doesn’t even understand what business it’s really in: not the code business (what is this, the 1980s?), but the enterprise of social interaction. That is not merely a matter of bits and bytes — but of norms and values. Hence, technology no longer understands the notion of quality in any meaningful way at all. “Quality” isn’t merely error-free code — but abuse-free interaction.
