A few of the developers with games in the rather fantastic Humble Indie Bundle 6 are hosting an AMA on Reddit right now.

In attendance is Runic Games co-founder Max Schaefer, representing Torchlight (and Torchlight 2, it seems); programmer Matt Bush and composer Terrence Lee of Dustforce's Hitbox Team; Jan Achrenius and Sampsa Lehtonen of Recoil and Rochard; Mario Wynands of Shatter's Sidhe, co-founders of MinMax Games Andrew Hume and Richard with Space Pirates and Zombies; and John Krajewski of Strange Loop Games representing Vessel.

Already the developers are discussing the likelihood of their Linux games on Steam, the benefits of being in the Humble Indie Bundle, and answering programming and gameplay questions galore. If you want to know what engines these guys use, how they handle physics or what those space pirates are doing hanging out with zombies in the first place, head on over to Reddit.
