I agree with the general sentiment that with as big of a war chest Steemit Inc has they should be able to hire the very best people and enough of them. However, the very soon upcoming hardfork will be the 20th one on Steem. The tone of the article is a bit too negative IMO. I'm basically optimistic about the future of Steem despite the problems we've had. Why? Because Bitcoin, Ethereum and other PoW chains touted in the article are nowhere near providing solutions to the scalability problem. If it really is that case that real-world adoption is what will make or break a blockchain in the next few years, Steem is better positioned than Ethereum. Transitioning into PoS will not be a walk in the park for Ethereum, that's for sure. Anyway, it's valuable that influential people call attention to the problems Steem has.
By the way, there is some value in these posts, too. Few whales dole out upvotes to such large numbers of smaller accounts like @berniesanders does here. Beats the shit out of vote selling.
