Why it is a bad/good idea? Worth trying?
What society really needs is less social media and social agent time. It's not good for us.
This is an attempt to kind of reduce screen time and power the genuine personal relations. If people can describe who they want to talk to or what news to get, that would make their presence online more thoughtful.
Another thing is easier content coverage - a user can describe what types of news from other people one does want to see, and the agent would send only those.
