Apparently, I succeeded but the feeds would still show up. These feeds refused to die! Annoyed, I sent them some feedback.
Today I got a reply from Ana Yang at FriendFeed. It is acknowledged as a known bug, and they’re looking into it right away. Kudos.
So, here’s to FriendFeed fixing themselves. Great job, Chief Miscellaneous Officer :)
And to the rest following my feed, many apologies for the current duplication in content. Hopefully the shared items make up for it!
