Everyone agrees that we should be writing in topics. (Okay, not everyone, probably, but everyone who is likely to read this blog.) Everyone agrees we should write in topics. But no one agrees on what a topic is.
Actually, that’s not entirely true. When asked to describe what a topic is, almost everyone in the business will come up with the same essential adjective: standalone. Everyone agree that a topic is a standalone piece of content. Unfortunately, no one agrees on what “standalone” means.
