My interpretation of this phenomenon is that significant (but subconscious) physical and social constraints are not removed from strangers who meet in person. There is risk and danger, there is wealth, language and vocalic register, and there is sexual politics. Humans evolved with these sociological pressures and most humans understand and conform to them.
But on the InterWobbles, people can be very wrong, flagrantly ignorant and completely inhumane without the probable damage to reputation (real-world personal cost).
Until their identities are leaked, of course... Then they realise the reputational cost of being wrong-headed, flagrantly ignorant, and inhumane. And they seek forgiveness ("escape from personal cost").
The InterWobbles have released the bottled demon and given us the 21st century's InterWobble Edition of Extraordinary Popular Delusions and the Madness of Crowds.[1]

And of course pure anonymity makes it possible to be an asshole without having to suffer the consequences.
Like someone else previously said, we need to invent a way to kick somebody's ass over the internet. Then we'll enjoy real time worldwide pleasant anonymity and thoughtful discussion.
It's perceived to be significantly more difficult to approach strangers in the real world, and successful relationships seem to fix people into whatever patterns initiated it.
Successfully developing the ability to approach strangers in real life is more potent than anything online - it can be unhealthy, as with pickup artists, or joining evangelistic cults, mlm, and so on, but socialization at that level seems to be a common trait among highly interesting people.
