It’s not related to the engineering side of things, but the Roomba subreddit would ban people for mentioning anything negative about the product, such a great way to keep your product “successful”.
My experience with HN is people generally prefer to dog pile onto whatever was mentioned, say it is the worst option, then bicker with each other about all the solutions being proposed. I say bicker, but those threads can be great sources of info.
Reddit is a weird place that is not real life.
i have never seen an HN thread about Reddit that didn’t turn into mostly hating Reddit.
Pretty much anywhere you go, people have a negativity bias both in what they say and in what they recall seeing. A great exception is Amazon reviews in which one must flip filters.
