Essentially, the Chinese government is choosing to block some of the most popular RSS feeds in the world. That’s like they decided to block the largest airline from their airspace. It is as close as you will see a nation coming to blocking the entire RSS/podcast transport. This goes beyond blocking blog services like TypePad and is important to watch. This might be a sign of bigger trouble for RSS in China.
Dave correctly notes that we should control our feeds and avoid centralization.
