I understand that links from Twitter and Facebook will pass through the paywall. As readers of this site know, I am preparing tools that route-around these Corporate Blogging Silos. I simply publish my links through RSS and depend on TwitterFeed to push them to Twitter. And the links should flow everywhere else, because RSS is so widely understood.
I hope to encourage many more people to do the same, and I think they will want to, as Twitter becomes more restrictive. I think this is in everyone's interest, except perhaps the owners of the CBS's. I believe independent publishers like the Times will eventually come to appreciate that there are options that don't flow through bottlenecks created by the tech industry.
Update: Mark Cooper says "all links will pass through the paywall."
