If you want to fix Reddit, come build the replacement with us! Our team of 5 at Upstream is creating a social content platform that combines crowd-sourced curation with machine learning to map the web by topic and surface relevant content for your interests. We also provide content recommendations from friends/influencers and help people create playlists of their favorite finds. We've built an alpha and are moving toward a public beta.

Email me at chris_alder@berkeley.edu if you're interested in seeing a demo. We're looking for skilled devs to join the team.
