I don't know if it will prevail in the end, but I think that Reddit approach by splitting the community in small subgroups/communities has a better chance to last in the long run.

Of course, you'll create feuds between communities but at least it is somewhat confined and not always spilling in the common public space.

Unfortunately it also greatly increases the echo chamber / filter bubble but it seems you can not have a peaceful community without an heavy dose of groupthink.

A long time ago, at the dusk of the XXth century, I used to believe that Internet would usher a new age of Enlightenment since every one would have access to many different opinions and unbiased sources. Arguably that was a pretty naive view, and instead we got new tribes disagreeing on almost everything conceivable.
