I call this idea the "feed marketplace" as opposed to "feed-as-a-service" which is what @openrank and others are doing. 

The challenge building a "choose your algorithm" is that the most interesting feeds are no longer just "algorithms" or fancy SQL queries.

For most users, what they say they want in a feed and what they actually do is a textbook example of stated vs. revealed preference.

They can only do what the app lets them. 

I’d argue 
Consumers want inspiring content & meaningful connections. 

How devs get there? Consumers could not care less.
