This is excellent:
Nothing says ‘you are not welcome in this discussion’ like jargon.
Smart writers avoid jargon as much as possible precisely because it excludes readers. A writer’s job is to engage and inform as many readers as possible.
Every piece of jargon, every difficult word makes that harder.
In technology it is all about the commercial case: companies who overdo the jargon lose sales to companies who can articulate ideas in plain English.
And often, the numbskulls who insist on jargon are the ones who are talking with forked tongues. It’s just the same with politics.
Plain English is radical.
