If you miss five days of reading the news because you were on vacation (good for you!) the newspaper you read the first day back isn’t five times as thick as the normal day’s paper. And it doesn’t have your name on the cover saying “Joe you haven’t read 1,942,279 articles since this paper started.” It doesn’t put you on the hook for not reading everything anyone has ever written. The paper doesn’t care, so why does your RSS reader?
Dave’s totally right. It’s one of the reason why I probably read more of my RSS feeds via Flipbook (which doesn’t punish you for not reading in this way) than Google Reader.
