Brent Simmons on why you should care about RSS, even if you don’t know what it is or what it stands for:
RSS is plumbing. It’s used all over the place but you don’t notice it. Which is cool.
This is elegance. It derives from the design of the internet and the web and its many open standards — designed so that no entity can control it, so that it survives stupidity and greed when it appears.
RSS is largely misunderstood. For example: any number of blogs that think limiting their feed will drive me to their web site.
