Welcome & I like your attitude!
Ultimatebass.com., primarily a site for freshwater bass fishing, is one that I frequent, and even it has dropped off a good bit as far as participation. There's a group of regulars who post often and those are mostly the staff members ( I'm staff there.) That site has a lot of members, with diverse fishing interests, but the majority are lurkers. I too use the same screen name on all sites.
I started a tackle business a few years ago, and am on both Facebook and Instagram, and only because of having a business. I stayed away from social media for a long time, but had to have a presence if I expected my business to survive. I refuse however to pay them for advertising, and simply keep making contacts and trying to respond to helping folks as I can. That's been a good way to be there as many don't share that attitude.
This site & Tidalfish are two that I've been on for a long time, and it's a shame what they are now compared to when I joined. I stayed signed up, but had not visited either in a long time, and last year came back. Things have changed over these years and I still prefer these forums to social media sites, but is the way of the world now it seems.
