Have you noticed these days how many things happen through webinars?
As someone who does not fear public speaking, I can't actually imagine interacting through a webinar. How do you read your audience when you cannot even see them?
All that aside, there are many days when I will have a webinar playing in the background as I'm answering emails, writing notes, signing paperwork, or other tasks that I can do while multi-tasking. (My husband might tell you that multi-tasking is not a great idea as I apparently don't always hear everything he says to me as I'm usually working on something else, too!)
I recently discovered that ASCD has a library of free webinars. As I tend to like to soak in lots of different learning...this is an exciting new hobby I have! (yes, I know, I need to get out more often!)
Check out the list of webinars here: http://www.ascd.org/professional-development/webinars.aspx
