If Lemmy and Mastodon continues to get popular, we will eventually get Instance wars.
If the descentralization of social networks continue, we will have to prepare for the eventual rise of the instances wars, where people will start to fight about which instance is better and which one is weird to be in and so on, but that's for the future of us all.
And the vast majority of the users consume the answers, not the discussion. They don't ask the questions, hey look them up, and if no one asked, or no one answered, they can't find anything and just give up. They don't ask.
Most communities do not like when people come in asking the same basic questions over and over again. I don't think you understand how link aggregators work.
reddit is a link aggregator. its for people to find links, post them to relevant groups who then evaluate the quality and relevance of that post, and then vote to bring it up or down in the feeds of people subscribed to that group. that's how reddit works. its a very poor way to hold discussions because it means any unpopular opinion gets downvoted by ignoramuses who don't understand that they're evaluating for quality not for agreement. reddit is not a place for discussion.
