That was far from a cheerleading session. He actually started off the article listing the problems. Perhaps yours could have been mentioned as well but what platform or technology doesn't have those.
As to Proof of Work vs proof of stake opinions may differ but I know where I stand and we'll see where things end up.
The only thing mentioned were early start-up issues, not the entire blockchain seizing up like a suburban dad having a heart attack from shoveling too much snow off of his driveway.
And no, the PoS vs PoW isn't an opinion - its technical merits and drawbacks that aren't touched upon, because every post about Steemit is rah-rah go team - instead of taking a hard look at why it functions the way it does.
Steemit is going to have to do something radically different to change that 13% retention rate, that's for sure. But I doubt they have the will to refactor a system they're obviously emotionally invested in.
I think that Steemit will fade into the background as other projects emerge on its blockchain. The seizing up that I've seen has been on other blockchains.
Interesting - care to list any? Also, were they PoS based?
Inquiring minds want to know...
