Respectfully, this is a small sampling of what's happening. Reddit and Twitter, the two posterchildren of poor management, have plenty of actual interaction. They also have a significant amount of shitty noise, which is incredibly off putting, but the average person is still more likely to go there than where our niche communities end up. They might be dying slowly, but they're not even on life support yet.
I think reddit is actually thriving. Everyone I know spends time there nowadays.
