What are the aspects you would recommend to pay attention to?
Specifically, we're organizing a seminar series, where we would also like to make the streams available online. It is not so important that the online observers are able to interact, so there could be some lag with the display online. In fact, having full chat interaction with observers like in "hangouts" could be risky, as someone from outside could interrupt the flow.
What are your recommendations on how to organize it? The aims of the stream is to allow people not attending to follow the discussions too and perhaps get more people interested through the shared link. It would be nice to know how many people are observing the link at the time. Otherwise, any ideas would be useful.
For example, we have been thinking about the balance of interaction and visibility of the online stream - it could be that if the stream is too comfortable, the participants might bother to show up, and just observe from home thus potentially unintentionally working against the seminar.
