This builds on a range of posts and commentary that have happened recently but is getting a lot of activity on twitter at the moment. Some of that interest is obviously circular, people who are on social media like the idea that social media is helping them.
I made the point that Jarret’s diagram as it stands at the moment doesn’t include linking, aggregation and the way that is important in supporting discovery as Edward said. Another way of viewing this is through the lens of a “link economy”, by analogy with Page Rank algorithms and this links through to how reputation economies are mediated. Is reputation simply appearing at the top of the relevant list of search results? Is it more granular. The two interact quite closely but I don’t have any simple ways of teasing them apart.
