We need niche content that is personalized, not just personalized mass media.

A reading list give us the general idea of interesting people on given topics.

We need to extract those relevant posts, plus others into niche categories of threads.

Links from posts aggregate threads.

Page Rank determines more important posts.

Past behavior determines another level of likely relevance

Past behavior tells if a portion of the link was read already, therefore, don’t show it.

Past behavior can be told by anonymous pools of metadata, attention recorders, cookies from contributing blogs, glistn click behavior

So organization happens at the post level even though community or social networking happens at the aggregate feed or reading list level.
