Is Twitter a Diverse Group?

Twitter is a great tool for creating an eclectic, like daily feed of interesting links and stimulus. I stumble across something through those, not so much in the tweets, but in the links and what people are pointing to. And it's a serendipity engine, right? It's constantly driving me towards new discoveries. Twitter has lost some of that in the sense that it's so dominated by the political conversation. We're living in a scary time politically and I understand that. But it still is a constant source of surprise and discovering that feeling of like, I didn't know that I was interested in this but I am.
