HungryFEED can't get feed: http://www.taz.de/Schwerpunkt-berwachung/!t10;atom/
I suppose HungryFEED is right: Todays feed says
<name>U. Winkelmann & C. Jakob</name>
with a plain ampersand which probably is not correkt!!!
Which WP filter could I use ('the_content' and 'content_edit_pre' seem to be to late...) to turn & into &???
