@lunduke Objective data can be validated, so you aren't always swimming in a dark pool of sources. Even subjective data can be held up against various observations, so it too can be categorized in a personal manner.

Once one has a data model, Twitter can be turned into an echo chamber via blocks and mutes.

Echo chambers can be invaded; even they require safeguards. Even without invasion, they can become twitter-like with too broad a subject matter.
