Pau Giner, Vibha Bamba, Jared Zimmerman, and I presented the Wikimedia Diversity Conference (https://meta.wikimedia.org/wiki/Wikimedia_Diversity_Conference) about how we're working to increase participation by reducing barriers.
If you're interested, the presentation slides are at https://commons.wikimedia.org/wiki/File:Engaging_new_editors_by_reducing_bar... , and the Etherpad is at https://etherpad.wikimedia.org/p/reducing-barriers
