All LiveJournal test users now have Atom feeds. Here is an example.
Simon Fell's Atom feed demonstrates explicitly marking the namespace on every item. More interestingly, he makes use of xml:base to have relative urls in links, ids, and even content.
Gordon Weakliem has created feeds for Amazon.com, and is exploring issues with dates and times.
(from Sam Ruby, pretty much verbatim ;-)
It's on the Livejournal test server at the moment (as you can tell from the url in the example link above), it's not live on livejournal in general.
Presumably it will be once atom gets ratified and the spec is ironed out.
