So, even within one group, if you can propose some statements that convince that group, then your statement flows to the top. On the other hand, if it bridges longer distance across groups, then on the global leaderboard, your message goes viral. So, basically virality is determined on how much distance do your statement cross to the other side. And so, this became essentially the same algorithm as community notes previously called Birdwatch on Twitter.com but now adopted by YouTube and Facebook and X.com.
