Flickr Feed Problem

I don’t know what’s going on, but it looks like my Flickr feed is suddenly posting plenty of pictures that aren’t mine. Anyone know what’s going on? Are other users experiencing this?

Update: Weird, if I view the feed in Safari it seems OK, but when viewed in Bloglines (I re-subscribed to the feed, just to make sure) I get a bunch of pictures that are not by me (and by people I don’t know).
