There are retired (time to participate) older men and women my age. It drops down by leisure time, and who would search for a forum in 2024. It's an old discussion format. I'm sure there are still people looking for list serves out there, but. Most fishtalk is elsewhere, with one or two line statements and questions.
My kids get their fish fixes from instagram, X and reddit. Great photos, less info.
We also have a bunch of younger members, and I get the sense a lot of the 'one thread question and out' members are in their 30s and 40s. We seem to have fewer dumb group attacks than other formats, again because I think forums are just not part of the culture anymore. I'm touching wood as I say that.
Most of the English speaking world seems represented here, along with a few people writing in what's not a first language.
As far as figuring people out, it doesn't matter. The less we know about each other up front the easier it is for us to make connections that survive the nasty polarization of our times. I like to know where in the world people are, as it's useful.
I have lost good internet friends in faraway places, and it can take months to find out what happened. Many of us lead compartmentalized lives. We don't always have any clear idea of who we're talking to, but we generally know what fish they like. That never gets into the obits.
