Hi,
A new episode of my MediaWiki podcast, "Between the Brackets", has been released - this one is an interview with Daniel Barrett, who was responsible for maintaining the MediaWiki instance at Vistaprint, and who is the author of the 2008 O'Reilly book "MediaWiki: Wikipedia and Beyond". You can listen or download it here:
