User blog comment:Brandon Rhea/New Page and Article Headers: Official Release Date/@comment-31403332-20170614064322/@comment-5558012-20170614135306

Adding categories near the top makes sense to me. I believe some of this dislike may stem in part from wikis that misuse or neglect categories. That's honestly a mistake on their part. I wrote Category Trees: Organizing a Wiki not long after the category addition to the header was made, for anyone who wants to improve the usefulness of this change.
