Add me to the list of Evernote users extremely disappointed with this. You could have at least emailed users that were having their feeds accessed to warn us. Now a bunch of stuff is broken for me. I haven't upgraded to a paid account because I haven't seen any reason to, but I would definitely pay for the ability to have an RSS feed of a public notebook. As it stands now, I will have to look for an alternate service to Evernote now, which deeply saddens me as I have been otherwise happy, even enthusiastic, about Evernote.
