It's written in pg's lisp dialect Arc. IIRC, a version of the news app is provided with the official Arc distribution, available here: http://www.arclanguage.org/install

See also the Arc Forum http://www.arclanguage.org/forum and the unofficial Anarki version of Arc (which, again, includes news.arc): http://github.com/nex3/arc/tree/master
