Many great comments here. I agree this forum is a reflection of the larger community or world we live in, forums by their nature a more impersonal community.
I don't know how many others feel this way, but whenever I get nostalgic about the good gone days of audio I think back to when I was first discovering audio, going to the dozens of high end audio stores here in southeastern michigan. The shows I attended, local shows as well in those days. I just loved the in person engagement with audiophiles much more knowledgeable than I, sort of like some exclusive club I wanted to get into. And yeah, that does reflect my high school need to be in a club or gang of cool people (and I did have that). I also had inherent or already converted audio buddies and other new converts, we all desired to own the best of the best.
On top of the need for socialization, I also had an inherent desire to learn about all aspects of audio, how components and parts work, and I loved to look at and touch these beautiful works of art.
So, there was all that. But then we mature, other things draw our attention, audio just another interest amongst many. While I maintained my interest in audio over all these years, equipment came and went, knowledge gained, the audio magic club morphed into being just another interest.
Perhaps some of us have short attention spans, highest interest when engaging in something new, interest gradually wanes as time goes on. I suppose these forums are the magic clubs of today for the newbies, and they still have shows and a few dealers to engage with. Sort of feel sorry for the newbies today, forums pale imitation of in person engagement, so few dealers and only national shows.
I'd say the one thing that sustains me is listening to great performances and music over a really fine, highly resolving system. The performers in room experience is one thing I never tire of!
