Give me an example of a business that is both good for the ecosystem and whose success depends on Steem itself to not function as a proof of brain content discovery and rewards token. Or give me an example of a project which would bring value to Steem whose prospects are hindered by Steem's ability to function as a content discovery token. I can't really think of any but I'm open to the possibility
The reverse is much more likely to be true: a working content discovery and rewards platform with a functioning front page will greatly attract real users and investors. This user base can then in turn be leveraged by businesses built using SMTs and Communities which will in turn bring more value to the system as a whole.
With the Steem economy how it is currently, voting rewards are predictably used as staking returns or payment, which is precisely how they should not be used. Profit minded businesses using voting rewards in lieu of transfer are far more likely to extract value from the system than contribute any real value themselves. And it's not their fault - we simply have the wrong economic incentives in place.
If we wait for SMTs and Communities on a broken system, when our front page is in disarray due to spam, bid bots and self votes and our alexa and cmc rankings are dropping steadily, how realistic is it to expect businesses built over this rotting core be able to garner the legitimacy and confidence required to only thrive itself but completely turn this place around? You're far more likely to get a few just extracting the dwindling value of this place and then moving on to greener pastures.
The underlying economy of Steem must be fixed. They're a higher priority than anything else and require far less investment, but they're the only change that can turn this place around and infuse value to every other endeavor we pursue (SMTs, communities, marketing etc.)
