That whole "niche communities" thing never rang true for me. I mean sure, if you like cast iron you can go to the cast iron community. And see 9000 pictures of cast iron pans and people freaking out about cast iron. Or cooking... and you have to listen to THOUSANDS of recommendations for air fryers but not cooking.
The "communities" system never worked from the word go. The site content should have been organized with weighted tags. As I find few things more nauseating than "collective intelligence" which is mostly wrong, ill-conceived, closed-minded and half-baked at best.
