The story of SNX should be inspiration for everyone building their own micro-economy. I mean, they were left for dead, and now some even argue that they are the #1 DeFi project in the space. Statistically, they probably will be once ETH2 launches. Vitalik is even participating in their v2 synthetix.exchange testnet.
It may well be that for the LEO token here, as it is not really finance-oriented in nature, that a halving is better for price appreciation. SNX needed to incentivize value brought into the ecosystem, so SNX inflation is used to compensate people for staking ETH and stablecoins into the ecosystem in order to make onboarding (into their synthetic versions of these assets, sETH and sUSD) as slippage-free as possible. The idea is that you need a seamless value transfer into and out of the SNX ecosystem in order to be encouraged to use it more.
For social media on the blockchain, it's a bit different. But yeah, I mean, it really comes down to how the founder best sees fit to bootstrap network effects, which can happen in all sorts of ways.
