What makes a good Conference proposal?

Relevance, being up-to-date, problem-solving, having a stance, opinionated: your proposal should be convincing with a well thought-out concept. re:publica participants and the programme team wish for content that deals with the challenges of our digital society, where we can learn something, be confronted with new perspectives and solutions, and be inspired. Or content that is simply fun. Of course, your proposal may or may not fit our motto.
