That website routinely comes up in a lot of crafts and craft-related hobbies (in my case, it was guns, where gunsmithing can involve parts they sell), so it's not exactly a secret. And yes, people do actually like it regardless of the article.

OTOH I don't know of any serious hobbyists (of whatever) who get the majority of their supplies from Amazon. When you ask, people generally say that selection is poor and quality is always highly suspect.
