In terms of the design, they cut through a lot of the bullshit developers and designers do on the web. The execution is great and there are a lot of high-fidelity details: the scale is on point, the text hierarchy is great, the use of colour is smart, it has a fantastic, almost brochure-like layout, and generally, the design is consistent throughout and plays an important role in customer experience and branding their product.
You're not their customer, they're not targeting Hacker News as a potential sales funnel. If your takeaway is the design team isn't interested in the product, I hope to God you don't work in web.
