You can't be so sure he's doing nothing; and like you said, this is decentralized; there's only so much he can do. The ones who can do things are the witnesses, and I'm sure they're all trying their bests to make things work.
Rome wasn't built in a day. We're still in beta. We might never be perfect, but five years from now when steem is way pass the moon, we'll probably look back on this and smile.
He controls millions in SP (which by the way is powering down through different accounts) and he chooses to support sketchy projects like @guyfawkes4-20 pointed out in the post. Also, from Dan's main account you can see that he withdrew more than 3 million STEEM over the last 5 months. Just some little facts.
And for the Rome part, I agree with you, but Steemit doesn't have 5 years as no other social media ever had. They either go mainstream or collapse way more faster than 5 years. (Steemit has already been around for about 2 years)
Lol. I think you're a little overexcited about moving to dan's eos platform--which doesn't even exist yet. I think it's cos you're fairly new to steemit.
Whales powering down is something that happens. It's nothing to panic about. Whales invest, whales power down. We'll be fine.
