Thank you Rasita! Had she not mentioned that my feed was down I never would have fixed the problem. Turns out my feeds to the Rocky Top Brigade had stopped and many readers went without my life influencing bits and bytes.
The probem turned out to be laziness. In one post I decided to turn on Blogger’s Compose tab and cut and paste from MS Word to Blogger. MS Word’s xml is horrible! And conflicted with Blogger’s Atom feed. The MS gibberish has been removed and everything returns to "normal."
