>Birdwatch doesn’t work by majority rules. To identify notes that are helpful to a wide range of people, Birdwatch ratings requires agreement between contributors who have sometimes disagreed in their past ratings. This helps prevent one-sided ratings.
This is something Elon Musk tweeted out recently. He seems to think that agreement on topic B by people who previously disagreed on topic A means they must be right on topic B.
The documentation is checked into GitHub[1]. It was checked in on March 2nd, 2022. This was a month before Musk bought his 9.2% share of Twitter.

It doesn't necessarily doom the system though, as long as people with extreme views don't outnumber more moderate people.
Of course the horseshoe effect is not some objective truth that's true in every country, that would be silly. I think the interesting part of it is that extreme ends of any political spectrum experience a similar environment: they are often shunned, distrust the mainstream media, attract social outcasts, etc. Just the shared experience of being on the edge of the spectrum often leads to similarities between them.
Often these few common topics overlap with the libertarian viewpoint.
Edit: unless we are talking about one or two party systems, there the dynamics are stranger
Speculation. Also, this system predates Musk's acquisition.
