I have been using Slido both in-person presentations and webinars. I have learned to use the polls to go beyond simple hand voting and get feedback on the types of things I want to know but require anonymity -- current job satisfaction, strengths and weaknesses of a product leader, stage of career. I also find it very helpful for Q & A where folks are more comfortable asking tough questions anonymously, and I love having a record in writing of all the questions -- helps me stay in touch with the audience. I now use Google Slides with the new integration so results pop up automatically for all to see. Fun. In webinar I use Google Slides + Zoom + Slido and it all magically works together.
