Trekkies and other hard-core sci-fi aficionados aren’t always thought of as the coolest kids on the playground. But TV personality Chris Hardwick has turned his dorkiness into an empire. His Nerdist is a cultural patchwork that covers music, art, books, and science; it’s also where you can listen to Hardwick’s podcast, which he describes as “basically just me talking about stuff and things with my two nerdy friends Jonah Ray and Matt Mira and usually someone more famous than all of us.” Those more distinguished guests have included Conan O’Brien, J.J. Abrams, and Zooey Deschanel. You can find programs hosted by dozens of others on the network as well, such as Sex Nerd Sandra, with sex educator Sandra Daugherty, and You Made It Weird, with comedian Pete Holmes. » New episodes are released weekly (days vary) at nerdist.com/category/podcast/.
