I recently gained access to the edit review queue and an enthusiastic member of the site is doing lots of cleaning up in my time zone, which is great.
Every now and then an edit consist of changing just the title from third person How do I...? to an impersonal How to...
My personal preference when searching for things leans towards the How do I...? approach so I am reluctant to approve the edit when that is the only change that is made. (Most often there are lots of other improvements).
Is there a preference? I couldn't find anything in the usual help files. Does it matter?
How about the difference between "File not found in..." and "How to find a file..."
Surely the people who need this site will just copy their error message into Google and see what comes up?
