We want to define main topics for the Wikimedia Developer Summit 2016, so that we can target better outreach and travel sponsorship beyond the usual participants in the event, and we can work better on the pre-scheduled sessions.
A Program committee is being created at the same time that these main topics are decided. It's a bit messy right now but things should settle soon. :)
The Summit will have plenty of time and space available to any other other topics pushed by their participants.
