One serious issue is that the Steem network currently has essentially no revenue. Everybody is acting all panicky about the market cap of STEEM dropping, but all of these author rewards are effectively being paid out of the market cap - because that's the only source of capital. All along, I've been saying that the game will change when advertisers find a good way to do their work on Steem; if advertising expenditures can be channeled into Steem Power, then the network will finally be on something like good financial footing.
