Out of all the things, Reddit is probably still the best for flashlight purchasing advice.

Somethingawful is still going strong, even after Lowtax died.

Here in Germany the forum culture is still somewhat alive, social media did take a big cut though.

I wish retro gaming was niche enough for nintendoage and assemblergames to still be around…

Plenty of console Homebrew and general gaming forums are still around. Like GBAtemp and ResetEra. I think all forms have really been about niche things for the most part. There were some general purpose forms but most of them focused around some Central subject that is core to their identity.

Truly general purpose platforms that attempt to be about everything weren’t really a thing until social media, with digg and Reddit.
