Another well-written piece on the Google Reader demise and the importance of RSS as a technology on the web. This piece on the difference between looking at a collection of RSS feeds vs. a Twitter feed is meaningful:
Trying to get caught up on more than a day or so of Tweets is virtually impossible for anybody who follows more than a few dozen active users — you simply can’t comprehensively take in the full stream. With RSS, on the other hand, you can scan through headlines and save them (or, yes, share them) and it’s possible to do so after a few days off the internet. Or a few hours. Woe betide the nine to fiver who wants to come home and quickly catch up on the day’s news via Twitter. Not everybody has the luxury of being able to keep tabs on Twitter all day. Twitter is realtime and RSS is time-shifted. Both are important. Just tell these same people you’re taking their DVR away and see what happens.
“Twitter is realtime and RSS is time-shifted.”
