<b>The predictable shape of a server's decline</b>

Communities don't usually die suddenly. The decay curve has a recognizable shape worth knowing before you're on it.

<b>What the data shows</b>
Longitudinal looks at Discord servers (and earlier forum lifecycle research) tend to find a three-phase arc: a steep early-growth honeymoon, a plateau where core regulars carry activity, then a slow exponential-looking decay as regulars depart faster than newcomers convert. Message volume often halves roughly every few months once decline begins, though rates vary widely.

<b>Why it happens</b>
The core does the emotional labor. When a founding regular leaves, they take their conversational gravity with them, and replacements rarely match it. Decay compounds because each departure makes the room quieter, which lowers the payoff of posting for those remaining.

<b>Discord vs Telegram</b>
Telegram broadcast channels decay differently — they can coast on passive subscribers long after real engagement is gone, masking decline behind a flat subscriber count.

<b>The caveat</b>
Survivorship bias is severe: we mostly study servers that lasted long enough to be studied. Dead-on-arrival communities rarely make any dataset.

Open question: is the plateau the moment to inject new structure, or does intervention just postpone an inevitable curve?
