Home Alone? How Content Aggregators Change Navigation and Control of Content
Every time someone makes a list, be it on a blog like Kottke’s or a list of groceries, content is aggregated. The act of aggregating content (usually content that is alike in some way) makes it more understandable. Instead of looking at a whole field of information, you choose smaller, more logical subsets of it in the hopes of understanding those. After you’ve done that, you can apply what you’ve learned to the whole, or even just a larger subset.
