Ok, this is about cliches, Winterfox - I wouldn't call these authors bad though - just feeding cliche dreams their readers (might) have. I originally meant a difference in humour though. Male/female humour differs in nuances.
One point I would like to add to your list => female authors use more details in their description of their environment, colours etc.
Devilish edit after Elliot's post:
Bad female authors write female characters as pure-hearted, beautiful and delicate yet deadly, intelligent and witty yet understanding, can engage in action with the best of them but still have amazing motherly instincts. "Strong" female characters, from them, are male-bashing and obnoxious (but get worshipped regardless).
Well, I'd call this a perfect, realistic and true description of every average
female in RL - (except the delicate and mother part, have to think about obnoxious, wish the understanding part would give way to evolution - finally, think we deserve worship in any case <img src="/ubbthreads/images/graemlins/shame.gif" alt="" /> Sorry, couldn't resist in a very pure-hearted way <img src="/ubbthreads/images/graemlins/evilgrin1.gif" alt="" /> )
