@scottspeaking There's a growing set of literature, though generally you could look at the rise and fall of movements, social groups, religious movements (look up the Second Great Awakening and Burned Over Districts sometime), etc.

My basic take is that there are two forces at play: (1) network effects though not the n^2 of Metcalfe's Law but some diminishing-return function (Odlyzko and Tilly suggest log(n): https://www.dtc.umn.edu/~odlyzko/doc/metcalfe.pdf) and (2) frictional costs which are more-or-less constant per node instance (though which can be modified across the network as a whole through various network-hygiene measures).

So, if you've got diminishing returns and constant costs, at some point adding another node no longer breaks even.

The pathological death spiral occurs when high value nodes start defecting from the network. This is the Yogi Berra effect: "Nobody (who's anybody) goes there anymore, it's too crowded (with everybody who's nobody)".

Danah Boyd has some great early work looking at the dynamic between Facebook (upstart) and MySpace (incumbent) in the mid/late aughts: http://www.danah.org/papers/talks/ICA2009.html

That's related to the Nazi At the Bar problem as described by @imaragesparkle at Birdsite: https://old.reddit.com/r/TalesFromYourServer/comments/hsiisw/kicking_a_nazi_out_as_soon_as_they_walk_in/. There are some founding / infiltrating cohorts who are so toxic that they lead to the flight of others. See generally Brain Drain and recognise that this can work in multiple directions for multiple groups, e.g., European Jews fleeing to the US whilst American Blacks fled to Europe. Same fundamental reason, but different dynamics affecting different groups. (This is also a #GreshamsLaw phenomenon, which is another trope of mine.)

I've written my own thoughts on why Usenet died, which Fedizens might want to consider. Not all the factors apply, though some do, upshot: it simply became too high-risk (and low-reward) to host Usenet: https://old.reddit.com/r/dredmorbius/comments/3c3xyu/why_usenet_died/
