Hi, I'm a co-found and developer at Steemhunt.
Steem is developing SMT because each dApp requires a different reward scheme and its own token economy.
Creating more tokens is not only good for project funding / bootstrapping, but also good for STEEM value. ETH has the second highest market cap because they have so many dApps and businesses built on the top of Ethereum platform thanks to ERC20 standard.
Steemhunt is built on SMT because we believe SMT has its unique advantage, and Steem has a potential to become more successful blockchain platform earlier than other general platform like ETH and EOS.
