As a fellow internet old timer, I agree that social media never really hooked me. I still spend vastly more time reading and posting on the SomethingAwful forums, which have been going for more than 20 years at this point, than I do Twitter. Maybe it's just "old man yells at cloud" and me refusing to change with the times, but I just strongly prefer the dynamics of forums.
Forums are also great for niche interests and communities. I used to be super into homebrewing beer (til kids happened), and there's a site called HomebrewTalk that was THE place to go to geek out on the hobby. People would share recipes, tips, photos of cool equipment they'd bought or built, industry news, etc. It's not something you can really replicate on Facebook or Twitter. I'm sure there is a homebrewing Twitter community, but by the nature of the app it's going to be much more what you're doing in the moment commentary than long form writeups preserved for all time. Both formats have their place.
