The way to play in the game in a user network is ESS.

In the 20th century, at least in the West, we were taught that games of life were zero sum.

But it turns out that in winning in the game of a user network economies you need a different strategy to win the game: evolutionarily stable strategy. Wikipedia says that "In game theory and behavioural ecology, an evolutionarily stable strategy^[1] (ESS) is a strategy which, if adopted by a population of players, cannot be invaded by any alternative strategy that is initially rare." see The Selfish Gene.
