As you know, we at Balanced are trying to encourage openness as well [1], but recently made the decision to not video record and publish (or live stream) guest speakers that come into our office. We feel this actually promotes a more honest and open discussion for the attendees. We may revise this decision, but it seems to be going well so far. We're also working on events specifically for remote audiences. Those will be recorded and published.
