This Meta discussion is based on some questions and suggestions about the title of one of my posts "The Lord of the Fields" on the main site.
As a general rule of SE sites it is recommended to add as much as possible information in the title of a post but as same as many other general rules there are some exceptions here. According to the special nature of some special posts which are special by their subject or writing style it is necessary to use an encrypted attractive title to show the difference of the post and hide its main subject for a while. Of course such titles should be meaningfully related to the body of the text but the important point is that one should discover this meaning during reading the post not before it. This journalistic approach in choosing titles of the articles increases the domain of audiences by exciting their sense of curiosity and make the post surprising and memorable.
Personally I believe adding or suggesting any edit on such special posts should be carefully designed because adding any too informative, long, formal or usual expression to the body or title of a special post can destroy the picture which questioner tries to describe entirely. Of course syntactical edits like correcting spelling and grammar are always fine but the edits which can change the nature, atmosphere and style of the post are potentially harmful for the general harmony of a special post.
As another example of special titling for special posts please look at the following cases:
Once upon a time there was a mathematician...
Question. What are nice harmony preserving approaches to edit a special post?
