RSS Overload and Why Tagging is No Solution

Thoughtful piece by Bill Burnham on RSS overload, its solutions, and why meta-feeds are better than user-added tags:

While tagging may be doomed to confusion, there are some other potential approaches that promise to bring order to RSS’s increasingly chaotic situation. The most promising approach involves something called a Meta-feed. Meta-feeds are RSS feeds comprised solely of metadata about other feeds. Combining meta-feeds with the original source feeds enables RSS readers to display consistently categorized posts within rich and logically consistent taxonomies. The process of creating a meta-data feed looks a lot like that needed to create a search index. First, crawlers must scour RSS feeds for new posts. Once they have located new posts, the posts are categorized and placed into a taxonomy using advanced statistical processes such as Bayesian analysis and natural language processing. This metadata is then appended to the URL of the original post and put into its own RSS meta-feed. In addition to the categorization data, the meta-feed can also contain taxonomy information, as well as information about such things as exact/near duplicates and related posts.

RSS readers can then request both the original raw feeds and the meta-feeds. They then use the meta-feed to appropriately and consistently categorize and relate each raw post.
