You are right, LinkLonk is a filter bubble. The difference from other systems (e.g., algorithmic feeds powered by machine learning that optimize for "engagement") that exhibit the filter bubble dynamics is that LinkLonk puts all of the control into the hands of the user. The user is responsible for the content they upvote which directly determines who they get content from in the future. In a sense this is similar to how users of RSS feed readers control which feeds they subscribe to. They are responsible for the content they consume. What LinkLonk adds is a transparent layer of automation that helps you subscribe/unsubscribe based on your content ratings. My hope is that LinkLonk will help people get more informed, but I cannot be sure. The project is a live experiment to find out if this is right system of incentives.
