RSS Feeds - Why do they bore me?

For more than a year I've subscribed to a half dozen RSS feeds and often I completely forget about them. Some are work-related and some are entertainment-related. Weeks will go by and they don't cross my mind and then I'll see all their names scattered across the top of my browser and I look at them again and usually yawn. I have not yet found any reason to prefer it over plain old email.
