>critiques mainly limited to the domain they have experience in i.e. the website.
They are giving actionable advice on how to convert more sales. That's the whole point of Show HN, and helpful to the author.
When a bunch of people with experience in a domain tell you that you can vastly improve something in that domain, it's generally a good idea to listen and consider their critique instead of calling them "keyboard ticklers".
I don't take issue with the critique per se, but the shallow and dramatic complaints about the website. In no way was the website "unusable" or "trash." If you wanted a photo of the brewer unit you could click through to the shop page.
No curiosity or questions or clarification about how it makes better coffee, spare parts availability, food safety, where and how it's assembled, thoughts about the aesthetics of the unit. Lots of "the site sucks, I bounced."
Edit: happily, there's more and better critique on the thread now than when I posted the GP comment.
