I dunno, when you’re talking about really specialized niches, there are still plenty of forums. Like, 600rr.net; it’s dedicated to nothing but Honda CBR600RR motorcycles. If you have a problem with a 600RR, the answer is probably there, and the forum is still ticking along because it’s just too hard to find those super-niche answers on Reddit. Want gun content with a healthy dose of homo/transphobia and christian nationalism? AR15.com has you covered. Want to talk about the minutiae of reloading and be autistically-focused on long-range accuracy? SnipersHide.com is your place. (They’re a bit fuddy though.)
