Hello  and thank you for your thoughts towards editing the Wikipedia article Ceiling fan  Your edits have been reverted because  Edit  Uses  vice versa in two story rooms the fact that a ceiling fan has a reduced effect when moved further away from the observers is a painfully obvious common knowledge and b is already covered in the Bases for comparison section subsection Perceived efficacy Edit  Uses  explain to define term stratifies the sentence Air naturally stratifiesthat is warmer air rises to the ceiling while cooler air sinks to the floor needs to be included as text because not all browsers notably textbased and slightly older ones can display that sort of popup text and not all users notice it and that exact text is essential to an understanding of why ceiling fans have a winter mode It is not longwinded or otherwise undeserved  In the future please make sure to request and discuss all of your proposed edits on the TalkCeilingfan talk page particularly if you are adding removing or altering statements of fact as opposed to say small grammar and spelling errors   Thank you for your many contributions
