Reddit is the big news right now, so that makes sense. It's news even outside of our own circle of technophiles and ex-redditors.
It's up to us to spread things out. A whole bunch of us are just waiting for someone else to take a step. If we take the step ourselves, people will join in, AND new users checking out the platform for the first time will see familiar things that make them feel like they've come to the right place.
