Hi,
There's a new episode out of my MediaWiki podcast, "Between the Brackets". In this one I talk to Clément Flipo, who started his MediaWiki career co-creating the tutorial site Wikifab, and now co-runs the consulting company Dokit, which creates tutorial sites for many others. You can listen to the episode here:
