> One thing I think you are missing is that in person groups are usually far smaller.

Yes, but — an online group with 1000 members isn't really equivalent to an in-person group with 1000 members. It's actually more equivalent in "activity" / "number of expected novel pairwise interactions" to an in-person group with, say, 150 members.

(Why? Because the "members" of an online group, as reported by most chat/forum systems, are just the number of people with access to the chatroom/forum, or who are subscribed to updates to the chatroom/forum, etc. Most of these people have never posted. Many more have only ever posted once. Whereas, in common parlance, you wouldn't really describe someone as a "member" of an in-person group, unless they actually regularly attend the group's in-person meetings. [And that goes double for formal in-person organizations, which often have membership fees or dues. Nobody bothers paying to maintain membership to these if they aren't intent on attending!] So the word "members" here really refers to two very different metrics: for online, the number of passive readers; for in-person, some upper bound on the number of people you might expect to encounter at the average in-person event. We need to do some unit conversions here in order to make valid comparisons!)

Let's say, for the sake of argument, that the average online group with 1000 "members" might have ~100 regular posters. (It's probably less, actually.) And let's also say that the average (geographically-based) in-person group with 150 "members", has events attended by ~100 people. And let's assume "regular posters" and "regular event attendees" are roughly equivalent in how they cause interactions that drive (dis)affection / (dis)engagement within the group.

I believe we both already agree that an in-person group where events regularly see ~100 attendees, tends to do just fine without rules of behavior / explicit moderation / etc.

And yet, it seems to me that an online group with "just" ~100 regular posters, almost always tends toward falling apart, unless it does have such rules, and moderation to enforce those rules.

That's the more specific, apples-to-apples-ish distinction that I had in my head in my GP post: that it's weird that when we take basically the same "level of expected interactions" from in-person + synchronous, to online + asynchronous, that it tends toward a different equilibrium state.

I do also agree with the lack of community / real relationships being a major driving factor. If you take a bunch of people who are already in the same community, and give them a closed-membership unmoderated online forum to speak in, the resulting interactions don't seem to tend toward awfulness/collapse nearly as badly.

But I would argue that this isn't just due to "consequences" (i.e. posters knowing they're impacting their position in the equivalent real-world community.)

Rather, I think a large part of what makes online forums "backed by" shared pre-existing communities more robust, is that the community provides its members with an implicit shared context for "recovering" an assumed set of nonverbal signals that "would go along with" others' textual wording choices... which in turn regulates behavior exactly as if those nonverbal signals were being explicitly communicated. People don't need to actually convey that they're frowning at you, if everyone in the community (including the poster!) knows exactly what subtextual meaning is carried by a reply of e.g. "Well bless your heart."

This is a testable proposition: it implies that closed-membership forums "bound to" a community offer no benefit, if 1. the community itself is open-membership and 2. new people join the community itself frequently enough that few community resources are being invested per new member on giving them a thorough enculturation into the community (incl. awareness of the community's wording-subtext equivalences.)

- So you would expect that, if there's an online community forum for e.g. a small village, where the only way to move there is to marry into an existing household there — then that forum will be robust and self-moderating, because every newcomer to that community gets a thorough dose of community enculturation.

- Whereas, if there's an online community forum for e.g. the congregation of a church in a particular urban neighbourhood of a city, where anyone can just rent an apartment in the neighbourhood and start attending the church... then that forum might be quite awful, despite every member being aware that what they say there will impact how the congregation sees them. Because there's no enculturative "speed limit" preventing absolute newcomers from immediately posting in that forum.
