As I read this article I found myself nodding my head. I’m much like Antonia and Colleen in the fac that I too think of webinars as “…a low-risk, easy, quick and cheap way to stay current about the state of the field…”
My personal experience has been that it’s hard to find the really good ones. I’ve seen most (if not all) of the pitfalls mentioned in the article but I don’t mind. I’ve come to see that often it’s easier to learn from non-examples (i.e. What not to do) than examples.
If you ever host / conduct online synchronous events you should go read this article to make sure you’re not making any of the mistakes mentioned.
If you do not make use of webinars as a personal learning tool you should definitely take a look at this and consider doing so. Webinars are a cheap (often free), low commitment way to learn and if it’s a bad session all you have to do it click out of it and move on.
