What do you imagine the impact would be on our global internet culture if online communities reflected monocultural values?

I know so much about other people, their cultures, and their lives, due to the internet. It has given me more empathy and understanding of the human condition than I would have had if I hadn't. If things were monocultural, we'd all be in our own little bubbles of what we're familiar with, and other cultures would be alien to us. That'd make it a lot harder to work together, and would create a HUGE cultural impact.
