I’ve seen this before (developing your own feed reader really takes you places); in this case, there seems to be a hidden (Unicode) control character in between the opening paragraph tag and the word “April.” One that, when I select and copy the surrounding text (and with it, this character) into my browser’s address bar, shows up as a “card” that reads “0010,” which might mean “data link escape.”

Actually, I’m seeing this post just fine precisely because I’ve instructed my feed aggregator to ignore this type of Unicode characters.
