You could build Steem apps that use Tron for smart contracts.

Yeah but the dapps will still exist on the Steem blockchain so the only benefit we would feel is if dapps manage to increase users and funding to improve our user experience.
Its not really a direct benefit for us.

DApps use blockchains as back ends, either as data storage (Steem) or for computing/data storage (Tron when using it for smart contracts). An app that used both Steem and Tron would benefit both blockchains by increasing organic demand for the tokens, that is SP, STEEM/SBD and TRX/possibly some TRC10 tokens.

steem is worth nothing

tron is worth a LOT but not by unit

steemit stinks at sales

tron stinks at coneheads

GET THE FUCKING PICTURE

PLEASE
