Internet communities comparison: what to know and why
An internet communities comparison on five observable axes: the membership gate, governance, moderation labor, exit cost and who owns the container.
People compare online communities constantly and almost always on the wrong axes. Size, activity and health are the three that get used, and none of them means anything without a definition nobody supplies. Meanwhile the properties that actually determine what a place is like to be in are rarely mentioned, because they are less visible from outside.
This page sets out what can be compared honestly, what cannot, and how to run a comparison whose conclusion would change if the facts were different.
What to take away
- Comparable: the membership gate, the governance model, where moderation labor falls, the exit cost, and who owns the container.
- Not comparable: size, activity, health, and anything requiring a count of people.
- Most published comparisons are ranking two places by how much the writer liked them, with the axes chosen afterward.
- A comparison is only useful if it names the decision it is meant to inform.
The five axes that work
| Axis | The question | Why it is observable | What it predicts |
|---|---|---|---|
| Membership gate | What must someone do to post? | You can attempt it | Arrival rate, and how much norm-teaching the place has to do |
| Governance | Who decides, and how are they chosen? | Usually published, and the gap between the published version and practice is itself visible | How conflicts end, and whether they end |
| Moderation labor | Who does the work, and are they paid? | Visible from who acts and how fast | Whether the place survives a surge of attention |
| Exit cost | What do you lose by leaving? | Enumerable: content, connections, standing, name | How much dissent the place can absorb before people leave |
| Ownership of the container | Who can close it, and who holds the archive? | A fact about the arrangement | Whether the community can outlive a disagreement with its host |
Two of the axes have a general literature behind them worth borrowing from. Exit cost is the ordinary economics of switching barriers, and moderation labor is a special case of who does unpaid work in a shared space, treated at length under content moderation.
Each of these is checkable without asking anyone for a number, and each of them changes what the place is like day to day. Exit cost is the one most often skipped and the one that explains the most: a community nobody can afford to leave produces a very different discussion from one people can walk out of, and neither is straightforwardly better. The mechanics of what is lost on the way out are set out under online status and identity.
Why size cannot be compared
A membership figure counts accounts that once registered. It includes people who left, people who never posted, duplicates and abandonments, and it does not include the people reading without an account, who are usually the majority. Two places reporting the same figure can have wildly different numbers of humans participating.
Active membership is worse, because "active" is a definition each place makes for itself, out of events it defines, over a window it chooses. The reasons a count of activity cannot travel between systems are the same ones set out under benefits of social media.
There is also a deeper problem. Size is not a property that ranks: a place of thirty and a place of thirty thousand are not the same thing at different scales, they are different kinds of thing. The thirty know each other. The thirty thousand cannot, so they need rules, roles and enforcement, and those are the things worth comparing instead.
Why health cannot be compared
"Healthy" smuggles in a purpose. A community optimized for newcomer support looks unhealthy to someone who values depth, and one optimized for expertise looks hostile to someone who values access. Both readings are correct given their premise, and the premise is what is being argued about.
Ask instead what the place is for, and whether its structure serves that. A place for beginners with a high membership gate is misconfigured. A place for specialists with no gate will spend all its time on basics and lose the specialists. That is a comparison with a fact of the matter in it, and it does not require anyone to agree about health. The families of complaint that get filed under this heading are sorted under critiques of social media.
A comparison procedure
- Name the decision. Where should I ask this question, where should I spend my evenings, where should we move the group. Different decisions weight the axes differently, and without one there is no basis for weighting at all.
- Fill the five axes for each candidate, from observation, not from the description on the front page.
- Note what you cannot observe, which will usually include how the place treats a disagreement, since that only shows up in one.
- Check the age and stage. A young community and a settled one differ in ways that have nothing to do with their design, and the stages are described under internet communities.
- State the conclusion as conditional. For this decision, on these axes, with these gaps. Anything stronger is a preference with a table attached.
What comparisons are usually for
Worth saying plainly: most published comparisons of online spaces are arguments in a dispute. Somebody wants people to move, or wants to justify having moved, and the axes are chosen to produce the answer. That does not make them useless, but it does mean the axes deserve more scrutiny than the conclusions.
Two ways to check. First, ask whether any axis would favor the other candidate, and if none does, the selection is doing the work. Second, ask whether the writer has actually participated in both, over enough time to see a conflict. Comparisons written from the outside describe the front page, which is the part designed to be described. The general reason outside descriptions of a group are unreliable is covered under generational digital culture, where the same error is made about age groups.
Common questions
Can I compare two places I have only read about?
You can compare their published rules and their stated governance, which is real information. You cannot compare what they are like, and the difference between those is where most bad writing lives.
Is a bigger community always harder to moderate?
Harder per moderator, yes, and the relationship is not simple: a large place with a strong gate can be easier than a small one with none. The gate and the labor are the axes, not the size.
What about comparing a community across time?
That is usually the more informative comparison and the harder one, because the earlier state is only visible through whatever survived. What survives, and what it leaves out, is set out under internet culture archives.
Which axis matters most?
Exit cost, for most decisions people actually face. It determines how much a place can ask of you before leaving becomes the reasonable response, and it is the axis nobody looks at until it is too late to look.
