The other way around makes sense too, but OG has a strong point. Some ads show you vibrant colors, sharp images and smooth motion. And somehow these advertisements look better as what you’re usually seeing on your screen. They show you what your new TV can do you on your old set up and that is somewhat crazy. It’s like an illusion. Maybe I’m crazy or stupid because I’ve been there and thought wow that new screen can really produce some nice images although I was watching it on my old TV.

Yeah the fragmentation isn’t great, but people usually flock together. For instance, you have multiple subreddits for franchises like Pokemon, but over time people will only use the most active or the most specific sub (each PKMN game has its dedicated sub). Plus I believe I’ve read somewhere that communities could be merged in the future. So if we don’t have two or more stubborn mods, that don’t want to work together everything should be fine, probably.
Sorry, I can’t help you, but what is vlemmy? A special kind of lemmy (different frontend etc)? Or was it a special community?
