Semantic Diffusion describes how terms lose their meaning as they spread. I discovered it a while ago. I think Event Sourcing, CQRS, and DDD are topics that suffer from this exact problem.
Shawn McCool discusses Event Sourcing as a modelling technique—how it differs from Event Streaming, why aggregates work better as short-lived lifecycles, and how CQRS pairs naturally with it. Touches on DDD as a pursuit of domain understanding.
