Being vague stinks. It’s kinda like trying forcing your readers to squint through a clouded window and then guess at what lies beyond. It’s not transparent, it’s not even semi-transparent. It’s opaque. If you want to share something, share it openly.
Don’t pretend to be open and sharing information when in reality you’re leaving only the roughest shadow of an idea in the minds of your readers. That’s not sharing. That’s not open. That’s frustrating.
