In discussion places where clutter accumulates in the workplace, I found this item and loved it (and not just for the workplace, either):
Language. Using buzz-words and let-met-try-to-impress-you language in your writing and speech can cause confusion, reduce productivity, and waste resources. A good rule of thumb is that if you can find the phrase in Unsuck-It‘s dictionary, you should think twice before using it. Direct language that is simple to understand will save you time and improve your communication skills.
