Writing Tip
Some sites, or their editors, change the title. Presumably the goal is either to pique the interest of a human reader, or to better align with Internet searches. Even if the title is changed, however, if you enter the article into the site's online editor, your original title becomes part of the URL and any hidden tags.
My first writing tip today is: try hard to craft your title both for human interest and for search engines.
My second writing tip is: trust your editor if the title is changed.
