Collaborative filtering

Instead of just filtering by keywords, could we vote entire posts up or down as to whether they’re interesting or not?

Then the votes of many users can be combined. But not just a popularity contest. If I vote similarly to User X, and User X downvotes a post, it can be assumed that I won’t like it either, and its priority can be minimized. If User Y and I don’t vote similarly, then their votes won’t affect what I see.

It’s a great approach, but it’s still a blackbox. I prefer to keep scores specific to you. I’m going to investigate this type of collaborative filtering next year when I work on v3 Intelligence. Right now I’m hands down in v2 Social and feed settings.
