Is there any guidance on the person to use when changing titles?

I have on occasion hesitated to add in the part that most OP leave out which is "How do I" or "how do you" or "how does one/do we" to take the usually terse subject phrase and turn it with minimal edititng into a full English sentence.

The best questions already have formed a great opening as they generally are "how exactly does x work" or "what step is needed between x and y"

Have other sites (or this one specifically) come up with a preferred wording for the sake of uniformity? Is uniformity even good - would it be better to have many voices?

Often the OP selects a person the body of the question so it is easy to maintain that voice.
