Contra to /MarketDiscipline, maybe the problem with amateur communities is that there is no other force holding them together. The moment they hit some problems, they dissolve.
In contrast, companies and institutions which are trying to preserve their own integrity, have some inertia or resistance which holds them together through the bad patches. And this gives them a valuable robustness. Maybe they form a virtuous kind of SlowNetwork.
Although your objections are occasionally relevant, I think there is something in the original suggestion.
However, I'm not sure that this is just about being a company. I think this is more to do with:
Other organisations that have both the size and import to keep going are churches and governments. I believe a whole bunch of seniour Eurpean Commission officials have recently uprooted to better pastures elsewhere ... but the EC will continue because a) it kind of HAS to and b) it's large enough to heal the 'wounds' of such a beheading.
So, maybe the problem for amateur groups is that they are typically small where the on-going existence of the group only matters to those directly involved. In this scenario the group is very vulnerable to the situation when a handful of the key people decide that they are not interested any more. There simply is no-one who cares enough (or is able to) pick up the pieces.
I love that notion of SelfHealingProperties?. (Gonna steal it for a page.)
And I agree that amateur groups tend to be small. But surely most companies are small. And these are held together by something else.
You make me realize things are a lot more complex than the simplifications on TheAgeOfAmateurs and this page.
All groups must put some energy into preserving their integrity. All productive groups must be AutopoeieticSystems?. So the only difference between working amateur groups and companies and other legally backed institutions is the degree and the flexibility of applying energy to preserving their own boundaries.
I'm sure size helps a lot. And I suppose big amateur groups can hold together through inertia.
I'm also sure demands from users help a lot. But I also suppose that there are different ways users can express their demands.
Of course, that's just the broadest classification. To understand anything I suppose you'd need to zoom into specific BusinessModels?, VotingModels etc before you could try to understand the forces protecting the integrity of the group or institution.
