That's certainly my hope for the federated model. Scope and scale have been issues since the advent of social media, which encouraged users to centralize all of their interactions in one spot. One hundred people shooting the shit on a specific interest will always be a better experience than orders of magnitude more people who know nothing of the context spouting off to feel good about themselves.
I found the quality of my Reddit interactions had gone so far downhill that I took a month off to start the year. I'd gotten sucked into the belief that upvotes == quality of what I was writing, which creates perverse motivations completely unrelated to being more informed about the world.
