I never thought about this.
For years, I have had 15 subscribers to my RSS feed.
Recently, I just got one more.
Should I toss it ASAP?
After reading your comment, I am leaning heavily in that direction.
Especially, since it is not a "new stuff" feed. It is merely a directory of all 20 subcategories on my site.
In trying to keep an open mind, it appears that what I have perceived as a positive feature, may in fact, be a red flag waving in the breeze. I don't want that.
