My approach to this is letting the interests of people I enjoy interacting with steer the ship a little bit. I can step a bit outside of my direct interests, for the sake of enhancing a relationship (and potentially expanding my horizons while I'm at it).

I remember @k00b making a really interesting point about what was lost when we gave up newspapers, though. Our environments are so curated now that we don't have easy avenues for random (and shared) information exposure.
