tag:flickr.com,2005:/photo/12345678

And in the RSS2 feed:

tag:flickr.com,2004:/photo/12345678

Notice the difference?  The photo ID is the same, the tag (a year, probably?) is slightly different.

I converted everyone’s Flickr feeds on whoisi to use RSS2 instead of Atom because the RSS2 feeds contain the thumbnail as part of the <media:thumbnail> element instead of having to make a separate call to the Flickr API.  This makes things like preview and adding new sites super-fast and it will probably let me remove a thousand lines of python and JS from the whoisi source code.

But the side effect was that with new IDs every entry looked new.  And I suddenly had a few thousand new entries in my unseen page on whoisi.  I spent some time last night and this morning cleaning up the database to reflect the proper GUIDs in flickr feeds.
