I've really been enjoying ranged touch network of podcasts lately. They have: Baldur's Gate replay podcasts (mages and murder dad's), Stephen King book podcasts (just King things), fallout games podcast (too much future), video game academia discussion (game studies study buddies), sci fi/fantasy book club (shelved by genre), A homestar runner retrospective podcast (homestuck made this world)

I think they're leftists, they're certainly anti-liberals at least, and they are funny and knowledgeable about things and I always learn more about anything when I listen to their content.
