True but, for example, I still find that restaurants and travel advice is far superior on Reddit than Google.
Reddit is often my starting point for beginning research on purchasing decisions.
Although when buying a digital piano, I ended up finding dedicated boards like pianoworld to be better
EDIT
Ironically, I also find YouTube to be a great source of research, mostly because the cost to produce content is higher and I think it's somewhat harder to produce inauthentic content (at least to me so far for the things I am researching)
Still, the high-quality advice on Reddit that is authentic can be the most useful stuff on the internet.
