We try to have a talk once a month and most of the time we just opened an issue on GitHub to find a topic, or someone willing to cover a topic we had on the list we gathered at the community meetup 2015.
However now with Discourse we can take a different approach. Please post topics that are Mozilla-related in this thread. Please keep it to one per post, so we can use likes to identify popular ideas in our community. Indicate if you’d like to talk about the topic you suggest yourself.
