>>24601082youtube's problem isn't a simple programming quality problem. they suffer from extreme dysfunction throughout all levels of management and leadership. there is no level of programmer that can make up for an organization that, overall, obsesses over shipping new and generally untested features, while at the same time huge numbers of severe revenue-impacting, brand-damaging bugs pile up in production and stay there without being addressed.
a company run by sane people would halt all work on new features, probably spending tonight completely ripping the chat raid attack and membership spam attack features out of production, and then ban all feature development for something like six to nine months to focus exclusively on stability and performance remediation. but youtube is not run by sane people.
