Netlify never misses an opportunity to self-promote in these SSG related threads, but AWS S3/Cloudfront/route53 is so cheap and simple for the audience that would even understand the point of Netlify, it's difficult to understand their target market. Netlify is priced like Squarespace, Wix, Weebly, etc. which are quite a bit simpler.
The fact that I can click on their homepage and drag-n-drop a site folder and have it just work is pretty damn slick. $39 is nothing if you don't have to deal with stuff. The absolute cheapest guys I work with are at least $50/hr. So if it saves an hour here and there it's worth it. And more likely, you'll spend 3-4 figures in time if there's any sort of hiccup in your AWS setup.
I don't think people are thinking how nice it is to have someone take care of stuff for you, totally. If there's any sort of issue, one email, and you're done. And people aren't thinking how tiny $39 is.
Again, I've never heard of Netlify before, but the product sounds great. HN is just messed up on pricing because they're looking at AWS costs instead of customer value.
I think HN also devalues their own time: I've been running webservers since the 90s, so I know it's "easy" to do, yet it's one more thing to have to think about. Although I suppose some might enjoy it.
