I was in my mid-twenties and my second marriage by the time I really got into internet forums, and they were mostly bicycle related ones. God only know how I'd have turned out if I'd been a teenager or Reddit or the like had been around. I think the closest thing at the time was slashdot, which I looked at briefly and noped the fuck outa there. Bikeforums.net is still alive and kicking, apparently.

I think the most important lesson I learned early on is that you're not going to change anyone's mind.
