This guy's site is not netflix nor facebook, nor is he 10k developers to support those architectures.
If this guy were pragmatic, a Ruby on Rails/django app in heroku would do wonders. If he wants to promote React because that's what he sells, that's a different story.
The problem is the people taking what this guy says as "the modern way to do it" and then you find the messes you find at work.
For anyone who's wondering: a repost invite is a way of getting a post into the second-chance pool (https://news.ycombinator.com/pool, explained at https://news.ycombinator.com/item?id=26998308), so it will get a random placement on HN's front page. If the original submission is older than a few days, we don't re-up it, but rather invite the submitter to repost it. Then it goes automatically into the pool. So yes, it's something good :)
