Sometimes, the hardest part of a presentation is getting feedback. So much time and energy is spent preparing for your conferences and presentations. You know your slides backwards and forward, you've done a mock presentation, revised, and practiced again. When it's all over and your conference is just a memory, you now have to sit back and wait to find out what people thought.
Sure, requesting an online survey after the conference is over is a great way to get feedback. There are a few snags to getting feedback this way. Your audience is busy and while they fully intend on giving feedback for your presentation, it might take them time to be able to submit their thoughts. It could be days or even weeks after your conference is over and you want to get feedback while things are still fresh.
Have you given any thought to asking for feedback while the conference is in live? Most web conference applications provide a way for you to ask for feedback through polls and allow asking more than one question. You can update your poll from "How do you feel about…" to "What is a subject you would like to see more about" with a couple of key strokes and you can get feedback instantly. There's no waiting, all the information is still fresh, and the web conference tool will store your poll results as well, so you can go back and look up to see the results later on.
How important is instant feedback when you're having a conference? Do you want to know right away the things that need to be adjusted or corrected, or are you more of the kind of person who prefers to wait until after you're done to get feedback so as not to have any distractions when you present?
