intertwingly

When it first appeared the White House feed had a few entries, all with the same id.  Now it has 87 such entries.  As first suggested by James Holderness, the feedvalidator now marks this feed as invalid.  It will do so for all feeds that contain ten or more entries all with the same id.  If this ends up producing too many false positives, I’ll tweak the algorithm.

Also noted in the process: the feed itself contains a fair amount of debris.  A sytle attribute?  A meta tag?  o:p is common in content carelessly copy/pasted from Microsoft Word.

script elements and onclick attributes generally aren’t syndication friendly.

Using the correct mime type and adding in a self link wouldn’t be a bad idea either.
