You know that RSS is catching on when American Idol has an RSS feed. I wonder what is the aggregator of choice for Simon, Randy, Paula, and Seacrest? Are they part of the 16 people that are subscribed with Bloglines? Perhaps now that the competion is into the final 12 contestants, hits on the Idol feed will increase just like Fox’s ratings. Unfotunately, with the technology’s limitations, you can’t “RSS” your vote for your favorite contestant. Maybe next year.
