If you are a presenter, please be sure to use a variety of media in your presentation. Incorporate a back channel or shared document, use video (edit it to be under 60 seconds - trust me on this one), and leave time for questions. Know your material and be sure there is at least one big takeaway related to your session description. Also, look at your slide deck and think about revamping the slides. Keep in mind that further information, resources and materials can be included on a website that you clearly post on your slides (in a shortened URL).
