Complex internet services fail in interesting ways as they grow in size and complexity. Twitter’s recent issues show how failures emerge slowly over time as relationships between components degrade. Meta’s quick launch of Threads demonstrates how platform investments can compound over time, allowing them to quickly build on existing infrastructure and expertise. While layoffs may be needed, companies must be strategic to maintain what matters most - the ability to navigate complex systems and deliver value. Twitter’s inability to ship new features shows they have lost this expertise, while Threads may out-execute them due to Meta’s platform advantages. The case of Twitter and Threads provides a lesson for companies on who they want to be during times of optimization.
Less code does not equal less readability. Less code comes naturally from SOLID, DRY principles and proper use of design patterns. Every one of those buzzwords emphasizes readability and maintainability. Throw in some DDD, and you have an excellent base for ever changing features.
