A mix of link aggregation and twitter (taking the best of both worlds) and than adding hierarchy by ratings from the link curators. This hopefully means avoiding suggestion engine clickbait, and democratic mainstream kitten pictures. It's always the 1 to 1 trust of subscriber and curator. This also goes away from timeliness and chronology.
Further experimental features:
- adjust your subscriptions by dampening or raising certain curators weighting
- meta subscriptions: Subscribe everything someone else subscribed to (with dampening when there are too many nested hops). Should take viral to an extreme (for good or bad).
- see each post only once (flip or scroll to the next page and it becomes permanently archived for you)
- nested folders and subscription based on folders (splitting personalities and allowing to split topics. In combination with meta-subscriptions one could subscribe to accounts of resort editors to make a "magazine")
If you are interested, I wrote a few pages about it I'll happily share.
