HN culture strongly discourages unsubstantive comments like "wow, this is great" that don't add to the conversation. It's hard to comment positively and substantively on a story like this, because it requires you to understand the subject matter well enough to describe some interesting feature, or bring up related work. It's usually much easier to find a flaw, or something that looks like a flaw to fellow non-experts. This comment section actually seems ok, but usually you'll see mostly neutral or negative comments.
