Feed normalizer allows ATOM syndication in Joomla

My website is now based on the Joomla content management system. I tried to syndicate a few of my friends‘ blogs (Gernot Starke and Markus Voelter) in the „Blogs“ menu of the website and found out that Joomla has problems with ATOM feeds – it simply cannot display them!
On the Net, I found Feed Normalizer, a nice and handy tool to convert ATOM and other feeds to RSS 2.0 which works perfectly with Joomla. It is a CGI script, it is written in Python and: it is open source! After installing Python, Feed Normalizer and Universal Feed Parser on my webserver, I can syndicate ATOM feeds, now. It still has some problems with German umlauts but that’s OK.
