I just noticed my Feedburner RSS Subscriptions have dropped from the usual 90s to 4. I was fiddling with Feedburner Newsletter. I don't know whether that had anything to do with it.
I apologise. Please come back.
Update
It seems Google has taken over Feedburner and forced us all into Google accounts. Although Google promises to transfer all the feeds, it has managed to lose all mine.
Thank you Google. I am really looking forward to the wonderful new services you are offering, if they are all like this.
