When I look at the list of folders and feeds in my account, there is one folder called “Artificial Intelligence”. (I don’t really remember creating such a folder, but let’s put that aside for now…) Looking in the web UI’s tree structure, this folder appears to not contain any feeds.
However, if I click on the folder, the content of two feeds “Chrome Experiments - Recent Experiments” and “BBC News - Home” appears in the story view for that folder. These feeds do not show up if I use the “All Site Stories” view (the typical way that I read new content).
Also, I am fairly sure that I removed these two feeds months or years ago. I attempted to remove them again just now, but they still appear in this mysterious “Artificial Intelligence” folder.
