I am finding the amount of questions left in "unanswered" state increase because the original poster had found the answer in the comments portion of their question and abandoned the question.
What can we do about these orphan questions that in fact have been answered/solved?
Apparently noticed almost a year ago by Mark Ireland here: Answering questions with a comment?
I particularly like @Casey's answer inside that Q&A.
And an example question that was solved and abandoned: Using local mbtiles in openlayers?
