Thanks to George for kicking my butt to try an RSS aggregator, showing me where to find SharpReader and how to use it...then encouraging me to at least attempt to create an RSS feed for my blog, which I did quickly using a simple service called RSSify. It's not perfect, but I was thrilled when I managed to add my feed to my list of RSS subscriptions.
Reading about RSS for months didn't really give me the sense of why it was valuable. But after trying SharpReader for about 30 seconds, I was converted. Pardon my newbie exuberance, but what an amazing research tool this is -- now I understand why the edutech bloggers have been so excited.
