But if you clearly don't have the domain knowledge required to make those judgements it really can be helpful.

I don't know anything about wine, and I really appreciate being told, "this is made my ____, they are super famous for ____".

then I can judge if I like it or not, regardless of how famous/old it is.

I also really like hearing other people's opinions and interacting with their excitement over "their thing" so ... to each their own I suppose.
