RSS Feeds

I explored RSS feeds by following Vidya Krishnaswamy's instructions on how to set up a gadget on my blog that links RSS feeds to the blog. I now have links to five episodes of "Unshelved" on my blog. Maybe this is a way of sharing information that you find valuable with the people who are following your blog. I guess it might also be a way to find it easily, but then again, if that's the case I am not quite sure why it's faster than the Favorites button.
