Podcasts Wk #9 --No. 21

I checked out a few of the podcasts, great to put a certain subject in and see what podcasts if any have been made. As for checking some of them out, one said not available, other said I had to install something??? I said "no" so not sure if I should have installed it or not, this was on my computer at my desk. Therefore, some podcasts, I didn't seem to have access to, but some I did see. It makes one realize there is so much more out there, on any subject, not just in print form anymore. Enjoyed this one, but still a bit confusing. I tried to add some podcast sites in my BlogLines account.
