> Anyone speaking in a "proper" session (...) > Anyone speaking in two or more lightning sessions In practice: the content committee needs to look carefully what lightning talks get approved, specially when they come from someone "unknown" in the community or difficult to evaluate based on e.g. other presentations elsewhere. Don't get me wrong. I'm overall happy on the selection of lightning talks and corresponding sponsored participants last year. But now I think that it was too easy to submit a proposal, get the corresponding sponsorship, deliver the 5 minutes and enjoy the weekend in Berlin. Maybe someone is tempted to exploit this "weakness" this year.
