The LinkedIn presentation was okay, but I would rather have had some concrete ideas than statics about how useful a site it is and how easy to find joint venture partners.
My favorite session was a blogger from Ottawa who started selling ads on her site a couple of years ago. It was interesting to see that she took her time and has added content almost every day since 1998. Her advice and the mistakes she's made were quite helpful to anyone monetizing their site that way.
I think all of the presentation notes were made available on the Podcamp 2011 Toronto website if you want more information. And if you've attended a podcamp in your area, I'd love to hear what you thought of it.
