If you have an important topic to cover, your discussion needs to reach out over social media. At the European Space Agency's "Paradigm Shifts and Future Prospects in Earth Observation" seminar, which was streamed live, the audience was asked to pose questions and comments to the panel via #FutureEO on Twitter. mimoLive was used to show the relevant tweets both in the live stream as well as on stage at the venue. The ESA social media managers only had to "favor" a tweet with the agency's account on their iPhones to make it appear in the stream and on stage instantly.
This is great for getting your audience engaged and promote your post: The Facebook Likes layer displays the "Reactions" to a post in your live stream. You can choose to show all types of reactions, or just a selection. This feature can also be used for voting by giving each reaction a meaning. (Please make sure to follow Facebook's guidelines for using the reactions for voting.)
