Payloads for Twitter. Friday, September 28, 2007 by Dave Winer.
Back in 2001, I wrote a document called Payloads for RSS that explained how you could attach something to a RSS item. I didn't explain how a RSS app would display or play one of these things, that would come later. Today, we may be at a similar place with Twitter. Sometimes I want to answer Twitter's question, "What are you doing? " Rest in Peace, RSS. It’s time to get completely off RSS and switch to Twitter.
RSS just doesn’t cut it anymore. The River of News has become the East River of news, which means it’s not worth swimming in if you get my drift. I haven’t been in Google Reader for months.
