Titles (or sub-titles) that help make the answer more readable, organized, etc. are good, and should be encouraged.
Example:
Stormtroopers are not poor soldiers. Let's consider the situations in
which they find themselves:
A New Hope: Soldiers on Tatooine are susceptible to Force Persuasion,
and are slow to break out the big guns to stop a freighter from
escaping. Stormtroopers on the Death Star show poor accuracy and
tactics during their pursuit of the main cast. Many seem to be killed
or wounded, and very few even come CLOSE to hitting the good guys.
Empire Strikes Back: Snowtroopers overrun prepared defenses at the
Rebel base. The Rebels are routed and flee. Later, Stormtroopers
escort Vader on Cloud City, essentially do nothing...except for
completely (and virtually invisibly) taking over the entire security.
Return of the Jedi: Storm and Scout troopers guard the forest moon of
Endor. A covert strike team supported by the indigenous peoples of the
moon assault the base and destroy it.
These are excellent uses of titles/section headers. They add organization and clarity to the answer.
Titles that are there simply because the author likes titles are noise, however, and should be edited out/discouraged.
Example:
Should Frodo have just flown over Mt. Doom and dropped The One Ring from the back of an eagle?
No, because that would have been a short and boring story. Here's why: lorem ipsem....
The title here adds no value, and should be removed.
