For a newbie to BYC it is not easy to sort which member has more knowledge or which member is just a newbie like them.
Look at the information in the side of the comments including many members avatar. It has so many tags and medals and information that is just too much for a newbie like me to know them when I am still a newbie.
It is like the medals of elite army leaders on their chest, they are so many of them shinning that if I see an army leader wearing them I would naturally say to myself : I am sure he/she knows his/her stuff , otherwise they would not have given him so many medals . So I tend to believe what he/she says.
I have no solution for it but it does not there is no solution for it.
It took me a few month of being in BYC and 50 comments or so to pay attention to the name of the member and start to sort it out that not all the comments are valid or has science behind it.
Hopefully others are sharper and faster than me to sort things out but if not one simple or simpler gauge that shows me the level of knowledge and experience of the commentator is not a bad idea. Maybe there is such a thing and I am not aware of it,
