Yesterday (I think), @srishakatux had a meeting with Melody on communication strategies for the Onboarding New Developer Program.
To not forget, filing a task.
In order to reach new audiences outside of our usual wiki sphere, use blogs / social media etc, by communicating why we do Onboarding New Developers, the Featured Projects on mw:New_Developers page, etc.
Add Wikimedia-Blog-Content to this task, once we feel ready. Might be September territory.
