I'm kinda glad Reddit is blowing up, it has been shit for a long time to be honest. Yes you can seclude yourself into smaller and more niche subreddits, but they all end up catering to the lowest common denominator eventually. If fediverse really kicks off I'm sure the same thing will happen in 10 years, but for now I'm excited to be trying something new
I disagree, you can use the fediverse practically forever as long as others are still using it. If an instance gets too big for your britches and you find the content has deevolved into low quality garbage, you can simply block it!
