unfortunately in my experience reddit still has more niche communities than can be found on lemmy, probably bc they have more users. they have more subreddits for specific games, cities/states, mental illnesses, spiritualities/world mythologies… the number of times I’ve searched for a community on lemmy only for it to not exist makes me hesitant to accept this video’s claim. reddit still has more niches than us. we just don’t have the numbers or activity.
