Writers , male or female have different style in writing. Similarly they have different tricks in answering questions. For example; a female don't know much about men's wear and a male don't know much about women's quality stockings. So their writing depends on the things they know not according to their gender.
Sometimes the article reveals what the author is all about. If it is forceful and rough maybe a man's. If it is more on feminine expressions maybe it is a woman. But this is not guaranteed because maybe he or she is a gay.
But one thing I believe and I read it somewhere; "Men responds from their mind but women responds from their hearts"
If not all but most.
