Convert any feed to ATOM
Judging by ATOM's rising popularity, see Atom compared to RSS, and its public endorsement by Google. Atom may be the future of Feed Syndication.
Here is a quick way, courtesy of Google, to convert any Feed type to Atom. Google provides a nice REST interface to convert your feed into ATOM. Just do a Get to http://www.google.com/reader/atom/feed/{url-to-convert}
e.g. To Convert MSDN RSS 2.0 feed (http://msdn.microsoft.com/rss.xml) do a GET on http://www.google.com/reader/atom/feed/http://msdn.microsoft.com/rss.xml. If you do View Source, you will see that it's converted to ATOM.
