Maybe you noticed that around April 1st your feedburner subscribers dropped—a lot. In our case 3/5ths of our subscribers abandoned us. Naturally I believed this to be a glitch and ignored it. Two days later I can firmly say that we’re still reading way below par.
On the advice of DavidF I checked out Google blog search and eventually found a post on the Feedburner help forum where MattS explained:
We checked this out and sure enough feedfetcher registered all of 1 subscriber for April 1st.
So have no fear, bloggers. The internet does not hate you.
