There are plenty of news subreddits. I greatly preferred /r/anime_titties, for example.
r/news has 26.34 million users. r/anime_titties has 0.47 (even you even somehow stumble upon r/anime_titties being a news/politics subreddit, as I didn't even know it existed until just now, and even then I didn't think "news" when I saw the name of it). Those are two drastically different experiences. Do you at least agree on that?
Then don't. I really don't understand what you think is going on here. If there's one community you prefer, stick with that.
I feel like you're not following the train of logic, here... we're discussing what happens when you can't/won't "stick with that".
They are not fragmented. In what way are they fragmented? Everyone can participate in communities on every instance, no matter where they are.
They are fragmented. Just because they can post somewhere doesn't mean they will. It's why !startrek has 4,870 subscribers, 190 threads, and 3,180 comments, and yet !startrek only has 810 subscribers, 10 threads, and 17 comments. If having the ability to post in multiple places meant people actually did post in multiple places, then !startrek would be a whole log more active, wouldn't it?
People don't need to leave that instance.
You're right, but they would need to start posting to whatever community/magazine I'm subscribed to, or else the community/magazine I'm subscribed to wouldn't have any content, and then why would I bother being subscribed to it?
Because Reddit's admins suck? Why else are you here?
If your only reason was because Reddit admins suck, you could have just quit the internet all together, but you came to kbin for a specific reason. You moved away from Reddit because of the admins, but you moved to kbin because of the content. Now imagine if there were no places with any content; you'd have nowhere to move to, and quitting the internet would be a more appealing option than posting in a magazine with 10 threads over 2 weeks.
