Podcasts

I am beginning to learn that all this technology is dependant on the user having a great internet connection - the podcasts took a long time to download onto my computer - a bit frustrating. I like the idea of using podcasts to introduce new books and services to the library. But then again would I have the time to create them ??? For the beginning it may be the option of choosing one application of Web 2.0 and roll with that for a while. So many choices........
