OSCON is the open source conference and the call for speakers just opened at https://conferences.oreilly.com/oscon/oscon-or/public/cfp/615.
Anyone from the ODK community interested in speaking, volunteering, or attending? It'll be July 16-19 in Portland.
I'm currently working on a talk I'll be giving to a local Write the Docs meetup:
Plenty Good Room: Hospitality in Open Source Documentation
I've submitted it to the main Write the Docs conference (also in Portland),
and have thought about submitting it to other places, like OSCON.
