Not just for news updates but for something that is just as important…price updates! It is so frustrating trying to buy plane tickets when you see how much the price fluctuates over time. If I wait another 15 minutes, will the price drop? But wait, if I don’t buy it now, will it go up?!? It’s so stressful.

I love that Travelocity created the RSS feed for plane tickets because it eliminates the need for me to compulsively check the Web site over and over again in hopes of finding a deal. It is a great use of RSS and one of the most useful ones I’ve run into so far.
