> If you're looking for more trustworthy product reviews than the ones on an Amazon product page

I totally believe that! But since I personally don't look for product reviews on the internet at all (and absolutely wouldn't look on Amazon), I wouldn't really know.

All I'm saying is that for the sorts of things I tend to search for, anyway, finding good resources on the web isn't that hard, so I never really understood why people prefer to search reddit (unless they already are reddit users anyway, of course).
