I feel I do benefit from what I read on here as it gives me information and alternative perspectives and when time permits I look into them in more detail, especially where people have provided links to read rather than just stated their opinion. That's why I keep coming back to this forum even if sometimes there are long gaps between posts.
But this is based on a presumption that none of us here are actually experts, and therefore that all we provide is a lay-person opinion, rather than an expert opinion. So the only time you'll get any expert opinion is if one of us posts a link.
Well firstly we all do this, including me - and you'll be aware that I tend to link to primary source information (original research) rather than a talking-head opinion piece. And also sometime apologise because I'm not clear whether a research article I can readily access may not be accessible to everyone. Why do you think that might be VG - any clues based on my profession.
But there is a further point - occasionally the expert is actually the person themselves. In that case their actual direct opinion is just as valuable, potentially more so, than a link to an 'expert' opinion. Specifically because they are actually the expert.
If you were discussing choral conducting with a highly experience professional choral conductor, why would you only be interested in their opinion if they provided a link to a blog written by another choral conductor. You can benefit from the expert opinion literally first hand.
Point being, for most of us, most of the time here we are all merely interested amateurs. But every once in a while we may touch upon something that one or other of us has a genuine expertise in. Rather than dismiss this, better to actually listen as you might actually learn something. That's always been my approach, but I guess as professional researcher I am inherently curious and genuinely want to learn from people who have expertise where I don't.
