Intriguing post by Dave Winer.

Now here’s a chilling thought.

If Twitter wanted to, tomorrow, they could block all links that went into a paywall. That would either be the end of paywalls, or the end of using Twitter as a way to distribute links to articles behind a paywall, which is basically the same thing, imho.

Twitter already has rules about what you can point to from a tweet, and they’re good ones, they keep phishing attacks out of the Twitter community, and they keep out spammers. But that does not have to be the end of it. And if you think Twitter depends on you, I bet Adobe felt that Apple depended on them too, at one point.
