Does other Audiogon members' opinion carry any weight for you ?

Of course. There's not as many great contributors as there were in my interest arena, but I'll take what's going.

Specific members carry weight nope. But as a collective community there are helpful responses. 
I was gone for a while and can say I miss carbonmiller’s musings. 

I'll keep it simple. I have been a member for over 20 years. Do I recall there being a more active era of members with enhanced knowledge and great personalities? Yes. Thing have changed a great deal. But I still learn so much from the regulars on this forum that offer solid and constructive critiques and insights. People on here know who they are. The forum is not dead. It's changing. As life does every day.

100%. I’ve only been on for a few years. I have selected my system around the comments and feedback from those group. I have listened when possible and also trusted. 

Opinion, no; knowledge, yes.
