In a networked era, there will be no destination, but rather a network of content and people. We cannot assume that content will be organized around topics or that people will want to consume content organized as such. We're already seeing this in streams-based media consumption. When consuming information through social media tools, people consume social gossip alongside productive content, news alongside status updates. Right now, it's one big mess. But the key is not going to be to create distinct destinations organized around topics, but to find ways in which content can be surfaced in context, regardless of where it resides.
Making content work in a networked era is going to be about living in the streams, consuming and producing alongside "customers." Consuming to understand, producing to be relevant. Content creators are not going to get to dictate the cultural norms just because they can make their content available; they are still accountable to those who are trafficking content.
