Heres an observation of writers on WordPress reader.
Go check out a list of posts under the business category, then go check out a category that involves the arts, photography, or something. Just look at the titles.
Business writers seem to be very good at getting the attention in the title. They get a point across real quick, while making it somewhat witty and catchy. Its usually 5-10 words.
Artistic writing is noticably much more thought provoking. It will only be maybe 2-5 words with each word seeming to have its own specific meaning in an attempt to capture all the content with very few words.
